If part of your problem is structured as a network,
then you may want to consider calling the ILOG CPLEX
Network Optimizer. This optimizer may have a positive
impact on performance. There are two alternative ways
of calling the network optimizer:
-
If your problem is an LP where a large part is a network structure,
you may call the network optimizer for the populated LP object.
-
If your entire problem consists of a network flow,
you should consider creating a network object
instead of an LP object. Then populate it,
and solve it with the network optimizer.
This alternative generally yields the best performance
because it does not incur the overhead of LP data structures.
This option is only available for the ILOG CPLEX Callable Library.
For more about formulating a problem in this way and applying the network
optimizer in your application, see this topic in the
ILOG CPLEX User's Manual.
