     A feasible circulation is an \f$f: A\rightarrow\mathbf{R}\f$
132 132
     solution of the following problem.
133 133

	
134 134
     \f[ \sum_{uv\in A} f(uv) - \sum_{vu\in A} f(vu)
135 135

137
     
137

	
138 138
     The sum of the supply values, i.e. \f$\sum_{u\in V} sup(u)\f$ must be
139 139
     zero or negative in order to have a feasible solution (since the sum
140 140
     of the expressions on the left-hand side of the inequalities is zero).
141 141
     It means that the total demand must be greater or equal to the total
142 142
     supply and all the supplies have to be carried out from the supply nodes,
143 143
     but there could be demands that are not satisfied.
144 144
     If \f$\sum_{u\in V} sup(u)\f$ is zero, then all the supply/demand
145 145
     constraints have to be satisfied with equality, i.e. all demands
146 146
     have to be satisfied and all supplies have to be used.
147

148 148
     If you need the opposite inequalities in the supply/demand constraints
149 149
     (i.e. the total demand is less than the total supply and all the demands
150 150
     have to be satisfied while there could be supplies that are not used),
151 151
     then you could easily transform the problem to the above form by reversing
152 152
     the direction of the arcs and taking the negative of the supply values
153 153
     (e.g. using \ref ReverseDigraph and \ref NegMap adaptors).
