Bound infeasibility column x1
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), CPLEX reports both the maximum scaled and unscaled feasibility violations.

WebApr 5, 2024 · This will list the constraints involved in the infeasibility. You can also use 'iisfind 2' which is slower but tries to find a smaller IIS. Sometimes AMPL's presolve capability gets in the way of using the IIS finder. AMPL runs a "presolve" step which attempts to reduce the size of the problem by identifying redundant constraints and so on. WebInfeasibility and unboundedness are closely related topics in optimization theory. Consequently, certain of the concepts for one will have direct relation to the other. As …
WebApr 11, 2024 · 4.2- Removing violating constraints and relaxing decision bounds. Once a suspected list of constraints and decision variables are generated, the problem can be reduced (in terms of constraints) and relaxed (with respect to suspected decision variable bounds) and resolved to determine whether the infeasibility issue is fixed.
