Infeasibility can be recognized when the optimality criterion indicates that an optimal solution has been obtained,and one or more of the artificial variables remain in the solution at a positive value.

Question

Quizplus · Accepted Answer

Infeasibility in linear programming problems is indicated when, after applying the simplex method or similar optimization techniques, the final solution includes artificial variables with positive values. These artificial variables are introduced to find an initial feasible solution, and their presence in the final solution with positive values means that no feasible solution exists that satisfies all the original constraints.
