Hi Renger, Thanks for your answer. In my purpose, I exactly want to minimize each ETA (ETA(1), ETA(2), ETA(3)) because I want to utilize some distributed algorithm. And p_pvf(i,t) is a variable in my future formulation. Could you give me some advice to write it under the rule "write one objective fu...

Re: the solver found integer solution

Hi Fred,
Thanks for your reply.
I have no idea to deal with my programm now. I just want to solve it with the status "1 optimal" through adding some constrains. In this case, could you tell me how to modify it?

Re: the solver found integer solution

Hi Fred,
The attachment (Untitled_2_log) should be the log file (reslim=30000), I'm sorry to make a mistake.
The GAMS and Cplex is a old version because I'm a student, and I cannot afford the License even the acadamic license. Thanks for your pertinent suggestion.

When I set reslim=30000, SOLVE SUMMARY is **** SOLVER STATUS 4 TERMINATED BY SOLVER **** MODEL STATUS 14 NO SOLUTION RETURNED Because of the Absolute gap is so huge and the converged s...

Re: the solver found integer solution

Hi Fred, Thank you very much for your reply. I set optcr=0 when the SOLVER STATUS is "1 OPTIMAL", and the result of MODEL STATUS is "1 OPTIMAL ". However, I guess the description of my model is not correct when the SOLVER STATUS is "3 resource interrupt". I tried to check the file of ''.lst'', but I...

Running the code I receive the SOLVE SUMMARY : **** SOLVER STATUS 3 resource interrupt **** MODEL STATUS 8 integer solution I went through the mod...
