Hi Zhang, first thank you for the great library. I'm using LINCOA as it's giving me good results compared to other optimization algorithms, but when I start Prima with LINCOA in several different thre…

I'm new to this library, let me know if this isn't the right place to ask this question.
I have called Minimize with no constraints (ie matrix A and vector B are both of size zero), and I get the o…

NLOpt supports COBYLA for constrained optimization, but I miss Powell's LINCOA (which uses quadratic approximation of the objective)
See: https://en.wikipedia.org/wiki/LINCOA + links therein

I noticed running LINCOA will make it regularly underrun set lower bound for a parameter, and cause my program to stop. Is LINCOA supposed to be bounds checked? If not, can you add the feature of boun…

Hi, I just wanted to suggest you to try the LINCOA method or BOBYQUA instead of the current simplex-based search in BiteOpt. It may provide a better convergence rate. Both are available in the [Prima …

Dear Prima,
A great thanks for developing so powerfull optimisation.
