search for: nonequality

Hi, I'm using optim with box constraints to MLE on about 100 data points. It goes quite slow even on 4GB machine. I'm wondering if R has any faster implementation? Also, if I'd like to impose equality/nonequality constraints on parameters, which package I should use? Any help would be appreciated. Thank you. rc

As part of a project to clarify what behaviour of C implementations is actually relied upon in modern practice, and what behaviour is guaranteed by current mainstream implementations, we recently distributed a survey of 15 questions about C, https://goo.gl/AZXH3S. We were asking what C is in current mainstream practice: the behaviour that programmers assume they can rely on, the behaviour
