 		Installation Instructions
 		=========================
 		Since you are reading this I assume you already obtained one of the release
 		tarballs and successfully extracted it. The latest version of LEMON is
 		available at our web page (http://lemon.cs.elte.hu/).
 		LEMON provides two different build environments, one is based on "autotool",
 		while the other is based on "cmake". This file contains instructions only for
 		the former one, which is the recommended build environment on Linux, Mac OSX
 		and other unices or if you use Cygwin on Windows. For cmake installation
 		instructions visit http://lemon.cs.elte.hu.
 		In order to install LEMON from the extracted source tarball you have to
 		issue the following commands:
 . `cd lemon-x.y.z'
 		      This command changes to the directory which was created when you
 		      extracted the sources. The x.y.z part is a version number.
 . `./configure'
 		      This command runs the configure shell script, which does some checks and
 		      creates the makefiles.
 . `make'
 		      This command compiles the non-template part of LEMON into libemon.a
 		      file. It also compiles the programs in the tools subdirectory by
 		      default.
 . `make check'
 		      This step is optional, but recommended. It runs the test programs that
 		      we developed for LEMON to check whether the library works properly on
 		      your platform.
 . `make install'
 		      This command installs LEMON under /usr/local (you will need root
 		      privileges to be able to do that). If you want to install it to some
 		      other location, then pass the --prefix=DIRECTORY flag to configure in
 		      step 2. For example: `./configure --prefix=/home/username/lemon'.
 . `make install-html'
 		      This command installs the documentation under share/doc/lemon/docs. The
 		      generated documentation is included in the tarball. If you want to
 		      generate it yourself, then run `make html'. Note that for this you need
 		      to have the following programs installed: Doxygen, Graphviz, Ghostscript,
 		      Latex.
 		Configure Options and Variables
 		===============================
 		In step 2 you can customize the actions of configure by setting variables
 		and passing options to it. This can be done like this:
 		`./configure [OPTION]... [VARIABLE=VALUE]...'
 		Below you will find some useful variables and options (see `./configure --help'
 		for more):
 		CXX='comp'
 		  Change the C++ compiler to 'comp'.
 		CXXFLAGS='flags'
 		  Pass the 'flags' to the compiler. For example CXXFLAGS='-O3 -march=pentium-m'
 		  turns on generation of aggressively optimized Pentium-M specific code.
 		--prefix=PREFIX
 		  Set the installation prefix to PREFIX. By default it is /usr/local.
 		--enable-tools
 		   Build the programs in the tools subdirectory (default).
 		--disable-tools
 		   Do not build the programs in the tools subdirectory.
 		--with-glpk[=PREFIX]
 		   Enable GLPK support (default). You should specify the prefix too if
 		   you installed GLPK to some non-standard location (e.g. your home
 		   directory). If it is not found, GLPK support will be disabled.
 		--with-glpk-includedir=DIR
 		   The directory where the GLPK header files are located. This is only
 		   useful when the GLPK headers and libraries are not under the same
 		   prefix (which is unlikely).
 		--with-glpk-libdir=DIR
 		   The directory where the GLPK libraries are located. This is only
 		   useful when the GLPK headers and libraries are not under the same
 		   prefix (which is unlikely).
 		--without-glpk
 		   Disable GLPK support.
 		--with-cplex[=PREFIX]
 		   Enable CPLEX support (default). You should specify the prefix too
 		   if you installed CPLEX to some non-standard location
 		   (e.g. /opt/ilog/cplex75). If it is not found, CPLEX support will be
 		   disabled.
 		--with-cplex-includedir=DIR
 		   The directory where the CPLEX header files are located. This is
 		   only useful when the CPLEX headers and libraries are not under the
 		   same prefix (e.g.  /usr/local/cplex/cplex75/include).
 		--with-cplex-libdir=DIR
 		   The directory where the CPLEX libraries are located. This is only
 		   useful when the CPLEX headers and libraries are not under the same
 		   prefix (e.g.
 		   /usr/local/cplex/cplex75/lib/i86_linux2_glibc2.2_gcc3.0/static_pic_mt).
 		--without-cplex
 		   Disable CPLEX support.
 		--with-soplex[=PREFIX]
 		   Enable SoPlex support (default). You should specify the prefix too if
 		   you installed SoPlex to some non-standard location (e.g. your home
 		   directory). If it is not found, SoPlex support will be disabled.
 		--with-soplex-includedir=DIR
 		   The directory where the SoPlex header files are located. This is only
 		   useful when the SoPlex headers and libraries are not under the same
 		   prefix (which is unlikely).
 		--with-soplex-libdir=DIR
 		   The directory where the SoPlex libraries are located. This is only
 		   useful when the SoPlex headers and libraries are not under the same
 		   prefix (which is unlikely).
 		--without-soplex
 		   Disable SoPlex support.
 		--with-coin[=PREFIX]
 		   Enable support for COIN-OR solvers (CLP and CBC). You should
 		   specify the prefix too. (by default, COIN-OR tools install
 		   themselves to the source code directory). This command enables the
 		   solvers that are actually found.
 		--with-coin-includedir=DIR
 		   The directory where the COIN-OR header files are located. This is
 		   only useful when the COIN-OR headers and libraries are not under
 		   the same prefix (which is unlikely).
 		--with-coin-libdir=DIR
 		   The directory where the COIN-OR libraries are located. This is only
 		   useful when the COIN-OR headers and libraries are not under the
 		   same prefix (which is unlikely).
 		--without-coin
 		   Disable COIN-OR support.
 		Makefile Variables
 		==================
 		Some Makefile variables are reserved by the GNU Coding Standards for
 		the use of the "user" - the person building the package. For instance,
 		CXX and CXXFLAGS are such variables, and have the same meaning as
 		explained in the previous section. These variables can be set on the
 		command line when invoking `make' like this:
 		`make [VARIABLE=VALUE]...'
 		WARNINGCXXFLAGS is a non-standard Makefile variable introduced by us
 		to hold several compiler flags related to warnings. Its default value
 		can be overridden when invoking `make'. For example to disable all
 		warning flags use `make WARNINGCXXFLAGS='.
 		In order to turn off a single flag from the default set of warning
 		flags, you can use the CXXFLAGS variable, since this is passed after
 		WARNINGCXXFLAGS. For example to turn off `-Wold-style-cast' (which is
 		used by default when g++ is detected) you can use
 		`make CXXFLAGS="-g -O2 -Wno-old-style-cast"'.

 		\brief Graph structures implemented in LEMON.
 		The implementation of combinatorial algorithms heavily relies on
 		efficient graph implementations. LEMON offers data structures which are
 		planned to be easily used in an experimental phase of implementation studies,
 		and thereafter the program code can be made efficient by small modifications.
 		The most efficient implementation of diverse applications require the
 		usage of different physical graph implementations. These differences
 		appear in the size of graph we require to handle, memory or time usage
 		limitations or in the set of operations through which the graph can be
 		accessed.  LEMON provides several physical graph structures to meet
 		the diverging requirements of the possible users.  In order to save on
 		running time or on memory usage, some structures may fail to provide
 		some graph features like arc/edge or node deletion.
 		Alteration of standard containers need a very limited number of
 		operations, these together satisfy the everyday requirements.
 		In the case of graph structures, different operations are needed which do
 		not alter the physical graph, but gives another view. If some nodes or
 		arcs have to be hidden or the reverse oriented graph have to be used, then
 		this is the case. It also may happen that in a flow implementation
 		the residual graph can be accessed by another algorithm, or a node-set
 		is to be shrunk for another algorithm.
 		LEMON also provides a variety of graphs for these requirements called
 		\ref graph_adaptors "graph adaptors". Adaptors cannot be used alone but only
 		in conjunction with other graph representations.
 		You are free to use the graph structure that fit your requirements
 		the best, most graph algorithms and auxiliary data structures can be used
 		with any graph structure.

 		@defgroup graph_adaptors Adaptor Classes for Graphs
 		@ingroup graphs
 		\brief Adaptor classes for digraphs and graphs
 		This group contains several useful adaptor classes for digraphs and graphs.
 		The main parts of LEMON are the different graph structures, generic
 		graph algorithms, graph concepts, which couple them, and graph
 		adaptors. While the previous notions are more or less clear, the
 		latter one needs further explanation. Graph adaptors are graph classes
 		which serve for considering graph structures in different ways.
 		A short example makes this much clearer.  Suppose that we have an
 		instance \c g of a directed graph type, say ListDigraph and an algorithm
 		\code
 		template <typename Digraph>
 		int algorithm(const Digraph&);
 		\endcode
 		is needed to run on the reverse oriented graph.  It may be expensive
 		(in time or in memory usage) to copy \c g with the reversed
 		arcs.  In this case, an adaptor class is used, which (according
 		to LEMON \ref concepts::Digraph "digraph concepts") works as a digraph.
 		The adaptor uses the original digraph structure and digraph operations when
 		methods of the reversed oriented graph are called.  This means that the adaptor
 		have minor memory usage, and do not perform sophisticated algorithmic
 		actions.  The purpose of it is to give a tool for the cases when a
 		graph have to be used in a specific alteration.  If this alteration is
 		obtained by a usual construction like filtering the node or the arc set or
 		considering a new orientation, then an adaptor is worthwhile to use.
 		To come back to the reverse oriented graph, in this situation
 		\code
 		template<typename Digraph> class ReverseDigraph;
 		\endcode
 		template class can be used. The code looks as follows
 		\code
 		ListDigraph g;
 		ReverseDigraph<ListDigraph> rg(g);
 		int result = algorithm(rg);
 		\endcode
 		During running the algorithm, the original digraph \c g is untouched.
 		This techniques give rise to an elegant code, and based on stable
 		graph adaptors, complex algorithms can be implemented easily.
 		In flow, circulation and matching problems, the residual
 		graph is of particular importance. Combining an adaptor implementing
 		this with shortest path algorithms or minimum mean cycle algorithms,
 		a range of weighted and cardinality optimization algorithms can be
 		obtained. For other examples, the interested user is referred to the
 		detailed documentation of particular adaptors.
 		The behavior of graph adaptors can be very different. Some of them keep
 		capabilities of the original graph while in other cases this would be
 		meaningless. This means that the concepts that they meet depend
 		on the graph adaptor, and the wrapped graph.
 		For example, if an arc of a reversed digraph is deleted, this is carried
 		out by deleting the corresponding arc of the original digraph, thus the
 		adaptor modifies the original digraph.
 		However in case of a residual digraph, this operation has no sense.
 		Let us stand one more example here to simplify your work.
 		ReverseDigraph has constructor
 		\code
 		ReverseDigraph(Digraph& digraph);
 		\endcode
 		This means that in a situation, when a <tt>const %ListDigraph&</tt>
 		reference to a graph is given, then it have to be instantiated with
 		<tt>Digraph=const %ListDigraph</tt>.
 		\code
 		int algorithm1(const ListDigraph& g) {
 		  ReverseDigraph<const ListDigraph> rg(g);
 		  return algorithm2(rg);
+		}
 		\endcode

 		/**
 		\defgroup map_adaptors Map Adaptors
 		\ingroup maps
 		\brief Tools to create new maps from existing ones
 		This group contains map adaptors that are used to create "implicit"
 		maps from other maps.
 		Most of them are \ref concepts::ReadMap "read-only maps".
 		They can make arithmetic and logical operations between one or two maps
 		(negation, shifting, addition, multiplication, logical 'and', 'or',
 		'not' etc.) or e.g. convert a map to another one of different Value type.
 		The typical usage of this classes is passing implicit maps to
 		algorithms.  If a function type algorithm is called then the function
 		type map adaptors can be used comfortable. For example let's see the
 		usage of map adaptors with the \c graphToEps() function.
 		\code
 		  Color nodeColor(int deg) {
 		    if (deg >= 2) {
 		      return Color(0.5, 0.0, 0.5);
 		    } else if (deg == 1) {
 		      return Color(1.0, 0.5, 1.0);
 		    } else {
 		      return Color(0.0, 0.0, 0.0);
+		    }
+		  }
 		  Digraph::NodeMap<int> degree_map(graph);
 		  graphToEps(graph, "graph.eps")
 		    .coords(coords).scaleToA4().undirected()
 		    .nodeColors(composeMap(functorToMap(nodeColor), degree_map))
 		    .run();
 		\endcode
 		The \c functorToMap() function makes an \c int to \c Color map from the
 		\c nodeColor() function. The \c composeMap() compose the \c degree_map
 		and the previously created map. The composed map is a proper function to
 		get the color of each node.
 		The usage with class type algorithms is little bit harder. In this
 		case the function type map adaptors can not be used, because the
 		function map adaptors give back temporary objects.
 		\code
 		  Digraph graph;
 		  typedef Digraph::ArcMap<double> DoubleArcMap;
 		  DoubleArcMap length(graph);
 		  DoubleArcMap speed(graph);
 		  typedef DivMap<DoubleArcMap, DoubleArcMap> TimeMap;
 		  TimeMap time(length, speed);
 		  Dijkstra<Digraph, TimeMap> dijkstra(graph, time);
 		  dijkstra.run(source, target);
 		\endcode
 		We have a length map and a maximum speed map on the arcs of a digraph.
 		The minimum time to pass the arc can be calculated as the division of
 		the two maps which can be done implicitly with the \c DivMap template
 		class. We use the implicit minimum time map as the length map of the
 		\c Dijkstra algorithm.

 		  without implementations and real data structures behind the
 		  interface. On the other hand they should provide nothing else. All
 		  the algorithms working on a data structure meeting a certain concept
 		  should compile with these classes. (Though it will not run properly,
 		  of course.) In this way it is easily to check if an algorithm
 		  doesn't use any extra feature of a certain implementation.
 		- The concept descriptor classes also provide a <em>checker class</em>
 		  that makes it possible to check whether a certain implementation of a

 		\page min_cost_flow Minimum Cost Flow Problem
 		\section mcf_def Definition (GEQ form)
 		The \e minimum \e cost \e flow \e problem is to find a feasible flow of
 		minimum total cost from a set of supply nodes to a set of demand nodes
 		in a network with capacity constraints (lower and upper bounds)
 		and arc costs.
+		and arc costs \ref amo93networkflows.
 		Formally, let \f$G=(V,A)\f$ be a digraph, \f$lower: A\rightarrow\mathbf{R}\f$,
 		\f$upper: A\rightarrow\mathbf{R}\cup\{+\infty\}\f$ denote the lower and
 		upper bounds for the flow values on the arcs, for which
 		\f$lower(uv) \leq upper(uv)\f$ must hold for all \f$uv\in A\f$,
 		\f$cost: A\rightarrow\mathbf{R}\f$ denotes the cost per unit flow
 		on the arcs and \f$sup: V\rightarrow\mathbf{R}\f$ denotes the
 		signed supply values of the nodes.
 		If \f$sup(u)>0\f$, then \f$u\f$ is a supply node with \f$sup(u)\f$
 		supply, if \f$sup(u)<0\f$, then \f$u\f$ is a demand node with
 		\f$-sup(u)\f$ demand.
 		A minimum cost flow is an \f$f: A\rightarrow\mathbf{R}\f$ solution
 		of the following optimization problem.
 		\f[ \min\sum_{uv\in A} f(uv) \cdot cost(uv) \f]
 		\f[ \sum_{uv\in A} f(uv) - \sum_{vu\in A} f(vu) \geq
 		    sup(u) \quad \forall u\in V \f]
 		\f[ lower(uv) \leq f(uv) \leq upper(uv) \quad \forall uv\in A \f]
 		The sum of the supply values, i.e. \f$\sum_{u\in V} sup(u)\f$ must be
 		zero or negative in order to have a feasible solution (since the sum
 		of the expressions on the left-hand side of the inequalities is zero).
 		It means that the total demand must be greater or equal to the total
 		supply and all the supplies have to be carried out from the supply nodes,
 		but there could be demands that are not satisfied.
 		If \f$\sum_{u\in V} sup(u)\f$ is zero, then all the supply/demand
 		constraints have to be satisfied with equality, i.e. all demands
 		have to be satisfied and all supplies have to be used.
 		\section mcf_algs Algorithms
 		LEMON contains several algorithms for solving this problem, for more
 		information see \ref min_cost_flow_algs "Minimum Cost Flow Algorithms".
 		A feasible solution for this problem can be found using \ref Circulation.
 		\section mcf_dual Dual Solution
 		The dual solution of the minimum cost flow problem is represented by
 		node potentials \f$\pi: V\rightarrow\mathbf{R}\f$.
 		An \f$f: A\rightarrow\mathbf{R}\f$ primal feasible solution is optimal
 		if and only if for some \f$\pi: V\rightarrow\mathbf{R}\f$ node potentials
 		the following \e complementary \e slackness optimality conditions hold.
 		 - For all \f$uv\in A\f$ arcs:
 		   - if \f$cost^\pi(uv)>0\f$, then \f$f(uv)=lower(uv)\f$;
 		   - if \f$lower(uv)<f(uv)<upper(uv)\f$, then \f$cost^\pi(uv)=0\f$;
 		   - if \f$cost^\pi(uv)<0\f$, then \f$f(uv)=upper(uv)\f$.
 		 - For all \f$u\in V\f$ nodes:
-		   - \f$\pi(u)<=0\f$;
+		   - \f$\pi(u)\leq 0\f$;
 		   - if \f$\sum_{uv\in A} f(uv) - \sum_{vu\in A} f(vu) \neq sup(u)\f$,
 		     then \f$\pi(u)=0\f$.
 		Here \f$cost^\pi(uv)\f$ denotes the \e reduced \e cost of the arc
 		\f$uv\in A\f$ with respect to the potential function \f$\pi\f$, i.e.
 		\f[ cost^\pi(uv) = cost(uv) + \pi(u) - \pi(v).\f]
 		All algorithms provide dual solution (node potentials), as well,
 		if an optimal flow is found.
 		\section mcf_eq Equality Form
 		The above \ref mcf_def "definition" is actually more general than the
 		usual formulation of the minimum cost flow problem, in which strict
 		equalities are required in the supply/demand contraints.
 		\f[ \min\sum_{uv\in A} f(uv) \cdot cost(uv) \f]
 		\f[ \sum_{uv\in A} f(uv) - \sum_{vu\in A} f(vu) =
 		    sup(u) \quad \forall u\in V \f]
 		\f[ lower(uv) \leq f(uv) \leq upper(uv) \quad \forall uv\in A \f]
 		However if the sum of the supply values is zero, then these two problems
 		are equivalent.
 		The \ref min_cost_flow_algs "algorithms" in LEMON support the general
 		form, so if you need the equality form, you have to ensure this additional
 		contraint manually.
 		\section mcf_leq Opposite Inequalites (LEQ Form)
 		Another possible definition of the minimum cost flow problem is
 		when there are <em>"less or equal"</em> (LEQ) supply/demand constraints,
 		instead of the <em>"greater or equal"</em> (GEQ) constraints.
 		\f[ \min\sum_{uv\in A} f(uv) \cdot cost(uv) \f]
 		\f[ \sum_{uv\in A} f(uv) - \sum_{vu\in A} f(vu) \leq
 		    sup(u) \quad \forall u\in V \f]
 		\f[ lower(uv) \leq f(uv) \leq upper(uv) \quad \forall uv\in A \f]
-		It means that the total demand must be less or equal to the
 		It means that the total demand must be less or equal to the
 		total supply (i.e. \f$\sum_{u\in V} sup(u)\f$ must be zero or
 		positive) and all the demands have to be satisfied, but there
 		could be supplies that are not carried out from the supply
 		nodes.
 		The equality form is also a special case of this form, of course.
 		You could easily transform this case to the \ref mcf_def "GEQ form"
 		of the problem by reversing the direction of the arcs and taking the
 		negative of the supply values (e.g. using \ref ReverseDigraph and
 		\ref NegMap adaptors).
 		However \ref NetworkSimplex algorithm also supports this form directly
 		for the sake of convenience.
 		Note that the optimality conditions for this supply constraint type are
 		slightly differ from the conditions that are discussed for the GEQ form,
 		namely the potentials have to be non-negative instead of non-positive.
 		An \f$f: A\rightarrow\mathbf{R}\f$ feasible solution of this problem
 		is optimal if and only if for some \f$\pi: V\rightarrow\mathbf{R}\f$
 		node potentials the following conditions hold.
 		 - For all \f$uv\in A\f$ arcs:
 		   - if \f$cost^\pi(uv)>0\f$, then \f$f(uv)=lower(uv)\f$;
 		   - if \f$lower(uv)<f(uv)<upper(uv)\f$, then \f$cost^\pi(uv)=0\f$;
 		   - if \f$cost^\pi(uv)<0\f$, then \f$f(uv)=upper(uv)\f$.
 		 - For all \f$u\in V\f$ nodes:
-		   - \f$\pi(u)>=0\f$;
+		   - \f$\pi(u)\geq 0\f$;
 		   - if \f$\sum_{uv\in A} f(uv) - \sum_{vu\in A} f(vu) \neq sup(u)\f$,
 		     then \f$\pi(u)=0\f$.
