baselpviolated

SCIP_Bool* DOMAINREDUCTIONS::baselpviolated

Indicates whether the base lp solution violates the new bounds of a var.

Definition at line 1400 of file branch_lookahead.c.

nviolatedvars

int DOMAINREDUCTIONS::nviolatedvars

Tracks the number of vars that have a violated (by the base lp) new lower or upper bound.

nchangedvars

int DOMAINREDUCTIONS::nchangedvars

Tracks the number of vars, that have a changed domain. (a change on both, upper and lower bound, counts as one.)
