    22=========================
    33
    4 Since you are reading this I assume you already obtained one of the release
    5 tarballs and successfully extracted it. The latest version of LEMON is
    6 available at our web page (http://lemon.cs.elte.hu/).
     4This file contains instructions for building and installing LEMON from
     5source on Linux. The process on Windows is similar.
    76
    8 LEMON provides two different build environments, one is based on "autotool",
    9 while the other is based on "cmake". This file contains instructions only for
    10 the former one, which is the recommended build environment on Linux, Mac OSX
    11 and other unices or if you use Cygwin on Windows. For cmake installation
    12 instructions visit http://lemon.cs.elte.hu.
     7Note that it is not necessary to install LEMON in order to use
     8it. Instead, you can easily integrate it with your own code
     9directly. For instructions, see
     10https://lemon.cs.elte.hu/trac/lemon/wiki/HowToCompile
     11
    1312
    1413In order to install LEMON from the extracted source tarball you have to
    1514issue the following commands:
    1615
    17    1. `cd lemon-x.y.z'
     16   1. Step into the root of the source directory.
    1817
    19       This command changes to the directory which was created when you
    20       extracted the sources. The x.y.z part is a version number.
     18      $ cd lemon-x.y.z
    2119
    22    2. `./configure'
     20   2. Create a build subdirectory and step into it.
    2321
    24       This command runs the configure shell script, which does some checks and
    25       creates the makefiles.
     22      $ mkdir build
     23      $ cd build
    2624
    27    3. `make'
     25   3. Perform system checks and create the makefiles.
    2826
    29       This command compiles the non-template part of LEMON into libemon.a
    30       file. It also compiles the programs in the tools subdirectory by
    31       default.
     27      $ cmake ..
    3228
    33    4. `make check'
     29   4. Build LEMON.
    3430
    35       This step is optional, but recommended. It runs the test programs that
    36       we developed for LEMON to check whether the library works properly on
    37       your platform.
     31      $ make
    3832
    39    5. `make install'
     33      This command compiles the non-template part of LEMON into
     34      libemon.a file. It also compiles the programs in the 'tools' and
     35      'demo' subdirectories.
     36
     37   5. [Optional] Compile and run the self-tests.
     38
     39      $ make check
     40
     41   5. [Optional] Generate the user documentation.
     42
     43      $ make html
     44
     45      The release tarballs already include the documentation.
     46
     47      Note that for this step you need to have the following tools
     48      installed: Python, Doxygen, Graphviz, Ghostscript, LaTeX.
     49
     50   6. [Optional] Install LEMON
     51
     52      $ make install
    4053
    4154      This command installs LEMON under /usr/local (you will need root
    42       privileges to be able to do that). If you want to install it to some
    43       other location, then pass the --prefix=DIRECTORY flag to configure in
    44       step 2. For example: `./configure --prefix=/home/username/lemon'.
    45 
    46    6. `make install-html'
    47 
    48       This command installs the documentation under share/doc/lemon/docs. The
    49       generated documentation is included in the tarball. If you want to
    50       generate it yourself, then run `make html'. Note that for this you need
    51       to have the following programs installed: Doxygen, Graphviz, Ghostscript,
    52       Latex.
    53 
     55      privileges to be able to do that). If you want to install it to
     56      some other location, then pass the
     57      -DCMAKE_INSTALL_PREFIX=DIRECTORY flag to cmake in Step 3.
     58      For example:
     59     
     60      $ cmake -DCMAKE_INSTALL_PREFIX=/home/username/lemon'

    5562Configure Options and Variables
    5663===============================
    5764
    58 In step 2 you can customize the actions of configure by setting variables
    59 and passing options to it. This can be done like this:
    60 `./configure [OPTION]... [VARIABLE=VALUE]...'
     65In Step 3, you can customize the build process by passing options to CMAKE.
    6166
    62 Below you will find some useful variables and options (see `./configure --help'
    63 for more):
     67$ cmake [OPTIONS] ..
    6468
    65 CXX='comp'
     69You find a list of the most useful options below.
    6670
    67   Change the C++ compiler to 'comp'.
    68 
    69 CXXFLAGS='flags'
    70 
    71   Pass the 'flags' to the compiler. For example CXXFLAGS='-O3 -march=pentium-m'
    72   turns on generation of aggressively optimized Pentium-M specific code.
    73 
    74 --prefix=PREFIX
     71-DCMAKE_INSTALL_PREFIX=PREFIX
    7572
    7673  Set the installation prefix to PREFIX. By default it is /usr/local.
    7774
    78 --enable-tools
     75-DCMAKE_BUILD_TYPE=[Release|Debug|Maintainer|...]
    7976
    80    Build the programs in the tools subdirectory (default).
     77  This sets the compiler options. The choices are the following
    8178
    82 --disable-tools
     79  'Release': A strong optimization is turned on (-O3 with gcc). This
     80    is the default setting and we strongly recommend using this for
     81    the final compilation.
    8382
    84    Do not build the programs in the tools subdirectory.
     83  'Debug': Optimization is turned off and debug info is added (-O0
     84    -ggdb with gcc). If is recommended during the development.
    8585
    86 --with-glpk[=PREFIX]
     86  'Maintainer': The same as 'Debug' but the compiler warnings are
     87    converted to errors (-Werror with gcc). In addition, 'make' will
     88    also automatically compile and execute the test codes. It is the
     89    best way of ensuring that LEMON codebase is clean and safe.
    8790
    88    Enable GLPK support (default). You should specify the prefix too if
    89    you installed GLPK to some non-standard location (e.g. your home
    90    directory). If it is not found, GLPK support will be disabled.
     91  'RelWithDebInfo': Optimized build with debug info.
    9192
    92 --with-glpk-includedir=DIR
     93  'MinSizeRel': Size optimized build (-Os with gcc)
    9394
    94    The directory where the GLPK header files are located. This is only
    95    useful when the GLPK headers and libraries are not under the same
    96    prefix (which is unlikely).
     95-DTEST_WITH_VALGRIND=YES
    9796
    98 --with-glpk-libdir=DIR
     97  Using this, the test codes will be executed using valgrind. It is a
     98  very effective way of identifying indexing problems and memory leaks.
    9999
    100    The directory where the GLPK libraries are located. This is only
    101    useful when the GLPK headers and libraries are not under the same
    102    prefix (which is unlikely).
     100-DCMAKE_CXX_COMPILER=path-to-compiler
    103101
    104 --without-glpk
     102  Change the compiler to be used.
    105103
    106    Disable GLPK support.
     104-DBUILD_SHARED_LIBS=TRUE
    107105
    108 --with-cplex[=PREFIX]
     106  Build shared library instead of static one. Think twice if you
     107  really want to use this option.
    109108
    110    Enable CPLEX support (default). You should specify the prefix too
    111    if you installed CPLEX to some non-standard location
    112    (e.g. /opt/ilog/cplex75). If it is not found, CPLEX support will be
    113    disabled.
     109-DLEMON_DOC_SOURCE_BROWSER=YES
    114110
    115 --with-cplex-includedir=DIR
     111  Include the browsable cross referenced LEMON source code into the
     112  doc. It makes the doc quite bloated, but may be useful for
     113  developing LEMON itself.
    116114
    117    The directory where the CPLEX header files are located. This is
    118    only useful when the CPLEX headers and libraries are not under the
    119    same prefix (e.g.  /usr/local/cplex/cplex75/include).
     115-DLEMON_DOC_USE_MATHJAX=YES
    120116
    121 --with-cplex-libdir=DIR
     117  Use MathJax (http://mathjax.org) for rendering the math formulae in
     118  the doc.  It of much higher quality compared to the default LaTeX
     119  generated static images and it allows copy&paste of the formulae to
     120  LaTeX, Open Office, MS Word etc. documents.
    122121
    123    The directory where the CPLEX libraries are located. This is only
    124    useful when the CPLEX headers and libraries are not under the same
    125    prefix (e.g.
    126    /usr/local/cplex/cplex75/lib/i86_linux2_glibc2.2_gcc3.0/static_pic_mt).
     122  On the other hand, it needs either Internet access or a locally
     123  installed version of MathJax to properly render the doc.
    127124
    128 --without-cplex
     125-DLEMON_DOC_MATHJAX_RELPATH=DIRECTORY
     126 
     127  The location of the MathJax library. It defaults to
     128  http://www.mathjax.org/mathjax, which necessitates Internet access
     129  for proper rendering. The easiest way to make it usable offline is
     130  to set this parameter to 'mathjax' and copy all files of the MathJax
     131  library into the 'doc/html/mathjax' subdirectory of the build
     132  location.
    129133
    130    Disable CPLEX support.
     134  See http://docs.mathjax.org/en/latest/installation.html for more details.
    131135
    132 --with-soplex[=PREFIX]
     136 
     137-DLEMON_ENABLE_GLPK=NO
     138-DLEMON_ENABLE_COIN=NO
     139-DLEMON_ENABLE_ILOG=NO
    133140
    134    Enable SoPlex support (default). You should specify the prefix too if
    135    you installed SoPlex to some non-standard location (e.g. your home
    136    directory). If it is not found, SoPlex support will be disabled.
     141  Enable optional third party libraries. They are all enabled by default.
    137142
    138 --with-soplex-includedir=DIR
     143-DLEMON_DEFAULT_LP=GLPK
    139144
    140    The directory where the SoPlex header files are located. This is only
    141    useful when the SoPlex headers and libraries are not under the same
    142    prefix (which is unlikely).
     145  Sets the default LP solver backend. The supported values are
     146  CPLEX, CLP and GLPK. By default, it is set to the first one which
     147  is enabled and succesfully discovered.
    143148
    144 --with-soplex-libdir=DIR
     149-DLEMON_DEFAULT_MIP=GLPK
    145150
    146    The directory where the SoPlex libraries are located. This is only
    147    useful when the SoPlex headers and libraries are not under the same
    148    prefix (which is unlikely).
     151  Sets the default MIP solver backend. The supported values are
     152  CPLEX, CBC and GLPK. By default, it is set to the first one which
     153  is enabled and succesfully discovered.
    149154
    150 --without-soplex
     155-DGLPK_ROOT_DIR=DIRECTORY
     156-DCOIN_ROOT_DIR=DIRECTORY
     157-DILOG_ROOT_DIR=DIRECTORY
    151158
    152    Disable SoPlex support.
     159  Root directory prefixes of optional third party libraries.
    153160
    154 --with-coin[=PREFIX]
     161Makefile Variables
     162==================
    155163
    156    Enable support for COIN-OR solvers (CLP and CBC). You should
    157    specify the prefix too. (by default, COIN-OR tools install
    158    themselves to the source code directory). This command enables the
    159    solvers that are actually found.
     164make VERBOSE=1
    160165
    161 --with-coin-includedir=DIR
    162 
    163    The directory where the COIN-OR header files are located. This is
    164    only useful when the COIN-OR headers and libraries are not under
    165    the same prefix (which is unlikely).
    166 
    167 --with-coin-libdir=DIR
    168 
    169    The directory where the COIN-OR libraries are located. This is only
    170    useful when the COIN-OR headers and libraries are not under the
    171    same prefix (which is unlikely).
    172 
    173 --without-coin
    174 
    175    Disable COIN-OR support.
     166   This results in a more verbose output by showing the full
     167   compiler and linker commands.

     39You can place your own C++ code using LEMON into this directory, which
     40will compile to an executable along with LEMON when you build the
     41library. This is probably the easiest way of compiling short to medium
     42codes, for this does require neither a LEMON installed system-wide nor
     43adding several paths to the compiler.
     44
     45Please have a look at <tt>contrib/CMakeLists.txt</tt> for
     46instruction on how to add your own files into the build process.  */

     393   strongly polynomial \cite klein67primal, \cite goldberg89cyclecanceling.
     394
     395In general, \ref NetworkSimplex and \ref CostScaling are the most efficient
     396implementations.
     397\ref NetworkSimplex is usually the fastest on relatively small graphs (up to
     398several thousands of nodes) and on dense graphs, while \ref CostScaling is
     399typically more efficient on large graphs (e.g. hundreds of thousands of
     400nodes or above), especially if they are sparse.
     401However, other algorithms could be faster in special cases.
    419402For example, if the total supply and/or capacities are rather small,
    420 CapacityScaling is usually the fastest algorithm (without effective scaling).
     403\ref CapacityScaling is usually the fastest algorithm
     404(without effective scaling).
     405
     406These classes are intended to be used with integer-valued input data
     407(capacities, supply values, and costs), except for \ref CapacityScaling,
     408which is capable of handling real-valued arc costs (other numerical
     409data are required to be integer).
     410
     411For more details about these implementations and for a comprehensive
     412experimental study, see the paper \cite KiralyKovacs12MCF.

     414minimum cost flow solvers.

    474468LEMON contains three algorithms for solving the minimum mean cycle problem:
    475 - \ref Karp "Karp"'s original algorithm \ref amo93networkflows,
    476   \ref dasdan98minmeancycle.
    477 - \ref HartmannOrlin "Hartmann-Orlin"'s algorithm, which is an improved
    478   version of Karp's algorithm \ref dasdan98minmeancycle.
    479 - \ref Howard "Howard"'s policy iteration algorithm
    480   \ref dasdan98minmeancycle.
    481 
    482 In practice, the Howard algorithm proved to be by far the most efficient
    483 one, though the best known theoretical bound on its running time is
    484 exponential.
    485 Both Karp and HartmannOrlin algorithms run in time O(ne) and use space
    486 O(n<sup>2</sup>+e), but the latter one is typically faster due to the
    487 applied early termination scheme.

     546\brief Algorithms for the symmetric traveling salesman problem
     547
     548This group contains basic heuristic algorithms for the the symmetric
     549\e traveling \e salesman \e problem (TSP).
     550Given an \ref FullGraph "undirected full graph" with a cost map on its edges,
     551the problem is to find a shortest possible tour that visits each node exactly
     552once (i.e. the minimum cost Hamiltonian cycle).
     553
     554These TSP algorithms are intended to be used with a \e metric \e cost
     555\e function, i.e. the edge costs should satisfy the triangle inequality.
     556Otherwise the algorithms could yield worse results.
     557
     558LEMON provides five well-known heuristics for solving symmetric TSP:
     559 - \ref NearestNeighborTsp Neareast neighbor algorithm
     560 - \ref GreedyTsp Greedy algorithm
     561 - \ref InsertionTsp Insertion heuristic (with four selection methods)
     562 - \ref ChristofidesTsp Christofides algorithm
     563 - \ref Opt2Tsp 2-opt algorithm
     564
     565\ref NearestNeighborTsp, \ref GreedyTsp, and \ref InsertionTsp are the fastest
     566solution methods. Furthermore, \ref InsertionTsp is usually quite effective.
     567
     568\ref ChristofidesTsp is somewhat slower, but it has the best guaranteed
     569approximation factor: 3/2.
     570
     571\ref Opt2Tsp usually provides the best results in practice, but
     572it is the slowest method. It can also be used to improve given tours,
     573for example, the results of other algorithms.

     66The \e LGF files can also contain bipartite graphs, in this case a
     67\c \@red_nodes and a \c \@blue_nodes sections describe the node set of the
     68graph. If a map is in both of these sections, then it can be used as a
     69regular node map.

    6683The \c \@arcs section is very similar to the \c \@nodes section,
    6784it again starts with a header line describing the names of the maps,
    … …  
    7996\endcode
    8097
     98If there is no map in the \c \@arcs section at all, then it must be
     99indicated by a sole '-' sign in the first line.

     101\code

    81109The \c \@edges is just a synonym of \c \@arcs. The \@arcs section can
    82110also store the edge set of an undirected graph. In such case there is
    83111a conventional method for store arc maps in the file, if two columns
    84 has the same caption with \c '+' and \c '-' prefix, then these columns
     112have the same caption with \c '+' and \c '-' prefix, then these columns
    85113can be regarded as the values of an arc map.
