 		\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 \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$\pi(u)<=0\f$;
 		   - 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
 		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$\pi(u)>=0\f$;
 		   - if \f$\sum_{uv\in A} f(uv) - \sum_{vu\in A} f(vu) \neq sup(u)\f$,
 		     then \f$\pi(u)=0\f$.

 		\brief Algorithms for finding minimum cost flows and circulations.
 		This group describes the algorithms for finding minimum cost flows and
 		circulations.
 		This group contains the algorithms for finding minimum cost flows and
 		circulations \ref amo93networkflows. For more information about this
 		problem and its dual solution, see \ref min_cost_flow
 		"Minimum Cost Flow Problem".
 		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 and arc costs.
 		Formally, let \f$G=(V,A)\f$ be a digraph,
 		\f$lower, upper: A\rightarrow\mathbf{Z}^+_0\f$ denote the lower and
 		upper bounds for the flow values on the arcs,
 		\f$cost: A\rightarrow\mathbf{Z}^+_0\f$ denotes the cost per unit flow
 		on the arcs, and
 		\f$supply: V\rightarrow\mathbf{Z}\f$ denotes the supply/demand values
 		of the nodes.
 		A minimum cost flow is an \f$f:A\rightarrow\mathbf{R}^+_0\f$ solution of
 		the following optimization problem.
 		LEMON contains several algorithms for this problem.
 		 - \ref NetworkSimplex Primal Network Simplex algorithm with various
 		   pivot strategies \ref dantzig63linearprog, \ref kellyoneill91netsimplex.
 		 - \ref CostScaling Push-Relabel and Augment-Relabel algorithms based on
 		   cost scaling \ref goldberg90approximation, \ref goldberg97efficient,
 		   \ref bunnagel98efficient.
 		 - \ref CapacityScaling Successive Shortest %Path algorithm with optional
 		   capacity scaling \ref edmondskarp72theoretical.
 		 - \ref CancelAndTighten The Cancel and Tighten algorithm
 		   \ref goldberg89cyclecanceling.
 		 - \ref CycleCanceling Cycle-Canceling algorithms
 		   \ref klein67primal, \ref goldberg89cyclecanceling.
 		\f[ \min\sum_{a\in A} f(a) cost(a) \f]
 		\f[ \sum_{a\in\delta_{out}(v)} f(a) - \sum_{a\in\delta_{in}(v)} f(a) =
 		    supply(v) \qquad \forall v\in V \f]
 		\f[ lower(a) \leq f(a) \leq upper(a) \qquad \forall a\in A \f]
 		LEMON contains several algorithms for solving minimum cost flow problems:
 		 - \ref CycleCanceling Cycle-canceling algorithms.
 		 - \ref CapacityScaling Successive shortest path algorithm with optional
 		   capacity scaling.
 		 - \ref CostScaling Push-relabel and augment-relabel algorithms based on
 		   cost scaling.
 		 - \ref NetworkSimplex Primal network simplex algorithm with various
-		   pivot strategies.
+		In general NetworkSimplex is the most efficient implementation,
 		but in special cases other algorithms could be faster.
 		For example, if the total supply and/or capacities are rather small,
 		CapacityScaling is usually the fastest algorithm (without effective scaling).

 		conservative if and only if there is no directed cycle of negative total
 		length. For an arbitrary length function, the negative of the minimum
 		cycle mean is the smallest \f$\epsilon\f$ value so that increasing the
 		arc lengths uniformly by \f$\epsilon\f$ results in a conservative length
 		function.
 		This group describes the algorithms for planarity checking,

 		- \ref Karp "Karp"'s original algorithm \ref amo93networkflows,

 		In practice, the Howard algorithm proved to be by far the most efficient
 		one, though the best known theoretical bound on its running time is
 		exponential.
 		Both Karp and HartmannOrlin algorithms run in time O(ne) and use space
 		O(n<sup>2</sup>+e), but the latter one is typically faster due to the
