The former version of lpx_check_kkt is correct, however, it lacks a check for complementary slackness, which is needed for basic as well as for interior-point solutions. The patch was incorrect just because in interior-point solutions variables have no statuses. > How about the preceding patch? Was that one correct? Or should the > unpatched GLPK 4.48 be used? glp_warm_up was patched correctly.
