Dear all,

I hope I find you well. Please help me, I run the model and it gave me the following report. I do not get a detailed solution results like that on page 23 of the gams tutorial (http://www.gams.com/dd/docs/gams/Tutorial.pdf). The results show that 2 locally optimum solutions were found. Is this ok or there are problems? How can I get the complete solution results?

Please see the summary below. Thank you for your time.

regards,

Loveness
