delcuts

Purpose

Delete cuts from the problem in the optimizer.

Synopsis

procedure delcuts(keepbasis:boolean, cuttype:integer, interpret:integer,delta:real, cuts:set of integer)

procedure delcuts(keepbasis:boolean, cuttype:integer, interpret:integer, delta:real)

Arguments

keepbasis

false	Cuts with non-basic slacks may be deleted
true	Ensures that the basis will be valid

cuttype

Integer number for identification of the cut(s)

interpret

The way in which the cut type is interpreted:

-1	Delete all cuts
1	Treat cut types as numbers
2	Treat cut types as bitmaps (delete cut if any bit matches any bit set in cuttype)
3	Treat cut types as bitmaps (delete cut if all bits match those set in cuttype)

delta

Only delete cuts with an absolute slack value greater than delta. To delete all the cuts set this parameter to a very small value ( e.g. -MAX_REAL)

cuts

Set of cut indices, if not specified all cuts of type cuttype are deleted

Further information

This procedure deletes cuts from the problem loaded in the Optimizer. If a cut is ruled out by any of the given criteria it will not be deleted.
