CPXXgetobjsen and CPXgetobjsen

The routine CPXXgetobjsen/CPXgetobjsen accesses whether the objective function sense of a CPLEX problem object is maximization or minimization.

int CPXXgetobjsen( CPXCENVptr env, CPXCLPptr lp )

int CPXgetobjsen( CPXCENVptr env, CPXCLPptr lp )

Description

The routine CPXXgetobjsen/CPXgetobjsen accesses whether the objective function sense of a CPLEX problem object is maximization or minimization.

Arguments

env: A pointer to the CPLEX environment as returned by CPXXopenCPLEX/CPXopenCPLEX.
lp: A pointer to a CPLEX problem object as returned by CPXXcreateprob/CPXcreateprob.

Return

A value of CPX_MIN=1 is returned for minimization and CPX_MAX=-1 is returned for maximization. If the problem object or environment does not exist, a 0 is returned.

Example


cur_objsen = CPXgetobjsen (env, lp);
