Detailed Description

components presolver

Dieter Weninger
Gerald Gamrath

This presolver looks for independent components at the end of the presolving. If independent components are found in which a maximum number of discrete variables is not exceeded, the presolver tries to solve them in advance as subproblems. Afterwards, if a subproblem was solved to optimality, the corresponding variables/constraints can be fixed/deleted in the main problem.
