lowerbounds

SCIP_Real* DOMAINREDUCTIONS::lowerbounds

The new lower bounds found for each variable in the problem.

Definition at line 1704 of file branch_lookahead.c.

Referenced by applyDeeperDomainReductions(), applyDomainReductions(), applySingleDeeperDomainReductions(), and selectVarRecursive().

upperbounds

SCIP_Real* DOMAINREDUCTIONS::upperbounds

The new upper bounds found for each variable in the problem.

baselpviolated

SCIP_Shortbool* DOMAINREDUCTIONS::baselpviolated

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

Definition at line 1706 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.

Definition at line 1707 of file branch_lookahead.c.

Referenced by applyDeeperDomainReductions(), applySingleDeeperDomainReductions(), isStoreDecision(), and selectVarRecursive().

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.)

Definition at line 1709 of file branch_lookahead.c.

nsimplebounds

int DOMAINREDUCTIONS::nsimplebounds

number of changed bounds resulting from infeasible child nodes
