expect_infeasible_problem:

Enable heuristics to quickly detect an infeasible problem. $\;$
This options is meant to activate heuristics that may speed up the infeasibility determination if you expect that there is a good chance for the problem to be infeasible. In the filter line search procedure, the restoration phase is called more quickly than usually, and more reduction in the constraint violation is enforced before the restoration phase is left. If the problem is square, this option is enabled automatically. The default value for this string option is "no".
Possible values:

• no: the problem probably be feasible
• yes: the problem has a good chance to be infeasible
