Networks are especially convenient for modeling because of their
simple nonmathematical structure that can be easily depicted with
a graph. This simplicity also reaps benefits with regard to algorithmic
efficiency. Although the simplex method of linear programming
is one of the primary solution techniques, we have already seen
that its implementation for network problems allows many procedural
simplifications. Small instances can be solved by hand and computer
programs are available for solving very large instances much faster
than standard simplex codes. This section provides a solution
algorithm for the pure network flow programming problem on a directed
graph.
