CPXgetbestobjval

Description

The routine CPXgetbestobjval() is used to access the objective function value of the best remaining node in the branch-and-bound tree.

The routine returns a zero on success; and a nonzero if an error occurs.

int CPXgetbestobjval (CPXCENVptr env, CPXCLPptr lp, double *objval_p);

Arguments

The pointer to the CPLEX environment as returned by CPXopenCPLEX().

A pointer to a CPLEX problem object as returned by CPXcreateprob().

A pointer to the location where the best node objective value is returned. If the branch-and-bound tree has been exhausted the best node value is set to a large number.

status = CPXgetbestobjval (env, lp, &objval);
