I coded a problem in two different ways. Similar types of equations –

one of them gives me global optimal solution whereas the other gives

me only locally optimal. I changed the solvers - all give me only

locally optimal solution. Is it due to equation structure? Is it

common to rewrite GAMS coding to achieve global optimality? What can

cause this (usually)?

Any tips will be very useful. Thanks

On behalf of Janos Pinter I post the following answer.

Subbu,

Systems of nonlinear equations often lead to global optimization

problems. You should try the GAMS global solvers.

Best wishes,

Janos
