- Solver: Mixed integer nonlinearly constrained optimization => AlphaECP:GAMS
GAMS Versus AMPL: it looks like a free solver is available as well, called MathProg. The syntax of AMPL is more natural/easier to read, it more closely resembles the algebraic formulations. After reading the first couple of chapters from the "AMPL: A Modeling Language for Mathematical Programming" book by Robert Fourer, David M. Gay and Brian W. Kernighan. Since the GAMS model seems to be pretty easy to understand, I see no problem in translating it to AMPL. I have to admit before stumbling upon these solvers while doing my thesis research, I had no idea about the existence of them ... but now I see the power of these solvers for optimization problems.
