Handling infeasibility

A problem is said to be infeasible if no solution exists which satisfies all the constraints. The problem status 'infeasible' generally is an undesirable outcome that should be avoided. In other terms, if an infeasibility arises you need suitable means to analyze what is going wrong and modeling techniques and tools to remedy or prevent this state from happening.

The following sections present different possibilities how to deal with infeasibility in FICO Xpress Optimization models.
