Hi Maddy. I’m looking that you have a inside the definition the max(0,a) function, maybe there is the problem because GAMS reformulates the DNLP problem in to a equivalent smooth problem and the MAX funtion is replaced for:

MAX(f(x),g(y)): ( f(x) + g(y) + SQRT( SQR(f(x)-g(y)) + SQR(delta) ) )/2 (see the CONOPT solver manual)

and there is the power function evaluated in zero. Maybe you can replace the 0 for a small epsilonand the problem is feasible.

Hope this helps

Best Regards
