Detailed Description

This class manages callbacks from the MIP solver.

The GLPK MIP solver calls method callback in the branch-and-cut algorithm. A listener to the callback can be used to influence the sequence in which nodes of the search tree are evaluated, or to supply a heuristic solution. To find out why the callback is issued use method GLPK.glp_ios_reason.

The listener list is stored in thread local storage. Each thread has to register its own listener.
