Summary 0000420: FIXED: BLEIC optimizer can fail when started from infeasible point
Description Feasibility solver used by BLEIC had flaw in the algorithm which prevented it from finding feasible points in some circumstances. It was replaced by better algorithm with guaranteed convergence (unless problem is so ill-conditioned that it is impossible to find feasible point because of rounding errors).
