Does anyone have a recommendation for a java numerical equation solver/maximzer? There are a lot of math utility libraries out there, and I thought folks out there, especially you EC types, might have tools/code libraries you have successfully used and trust. Perhaps someone recommends a library for constrained optimization of linear/non-linear functions? mike Michael Makowsky Graduate Student Department of Economics George Mason University 703.608.1366 [log in to unmask] website: http://mason.gmu.edu/~mmakowsk
