I assume you mean ≤ 0. This is effectivley an equality constraint, C(x) = 1. However, as explained in the documentation, MMA does not support equality constraints in any form — technically, it requires the feasible set to have a non-empty interior. So, it's not surprising that it fails. _______________________________________________ NLopt-discuss mailing list NLopt-discuss@ab-initio.mit.edu http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/nlopt-discuss
