Strange problems about initial point of JAMS solver

Dear All, I now have a very strange problems when use jams solver to solve a MOPEC problem. To solve my MOPEC, I will first solve a very similar system optimization problem to get a feasible initial point. (It is feasible since when I fix this initial point and solve the problem, the model status is...

solver problem for solving a series equilibrium problem

Dear GAMS communities, I am now trying to solve a series of equilibrium problems and analyze the sensitivity analysis of the value function on the initial input state value. However, now I have a problem that a large part of these problems model status will be: 5 locally infeasible after solving. Fo...

Syntax error for EMP equilibrium problem

Hi, I am trying to write a gams model with emp input to solve a equilibrium problem. However, GAMS said I have a syntax error causing JAMS Pre processing failed that I don't know how to deal with: *** EMP syntax error: key expected: is I (item 13 on line 3) but instance not in variable rim Here is t...
