WebThe infeasibility reporting by the Xpress Optimizer separates information into information relating to constraints and information relating to variables, the latter includes the bounds and for the MIP case also the variable type - see for example the documentation of the routine ' XPRSgetiisdata ' that shows the different possibilities, Mosel ...

WebAfter it finds an optimal solution, it then checks for any violations of optimality or feasibility in the original, unscaled problem. If there is a violation of reduced cost (indicating nonoptimality) or of a bound (indicating infeasibility), ILOG CPLEX reports both the maximum scaled and unscaled feasibility violations.
