In this case the numerical status code does not encode whether a feasible solution exists and whether that solution is primal or dual feasible. Parameters: status - The numerical status code. pfeas - The primal feasibility that CPLEX reported for the optimization that returned status. dfeas - ...
Each inequality constraint is subjected to a simple test to determine if there exists any setting of the variables (within their bounds) that can violate it; if not, it is dropped as nonconstraining. Further iterative tests attempt to tighten the bounds on primal and dual variables, possibly ...
