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
