Member Function Documentation

status SCIL::submodular::feasible ( solution  )  [inline, virtual]

This function is called, if the BCP-System wants to save the solution of the LP-solver as primal solution. If this function if called, it is guaranteed that all interal variabes have integral values in the LP-solution. The function should return either feasible or infeasible. It could also return fathom, preemtion, exception_branch or resolve_immedialtely.

Reimplemented from SCIL::sym_constraint.

Definition at line 31 of file submodular.h.

References SCIL::solution::value().

virtual void SCIL::submodular::init ( subproblem  )  [inline, virtual]

This function is called before the first LP at the root of the BCP-tree is solved.

Reimplemented from SCIL::sym_constraint.

Definition at line 25 of file submodular.h.

submodular::status submodular::standard_separation ( subproblem  )  [virtual]

This function is called if the BCP-System wants to cut of the solution that was found by the LP-solver. It should return either no_cons_found or cons_found. But it is also possible that it returns fathom, preemption, exception_branch, or resolve_immediately.

Reimplemented from SCIL::sym_constraint.
