Hi everyone

I am running a model which has a min max function but I dont have the results that I need.

Basically I have a parameter inside my model. After the model calculating this parameter, I need to minimize the biggest result of this parameter.
How can i do this?

Hi,
okay and how can i reformulate my model? Which parts should I focus on especially?

Hi everyone!

I added these two line to my model but it still gives me very big absolute gap and I can not trust my optimal result.


option optcr = 0;
Option optca=0;

How can i lower these gaps?

Hi,

This is what I am still searching

My aim is making a continuous area instead of discrete area.

Hi, I tried to use this logic but my aim is creating a contunious area as sum of the all places. For example I have a 1x1 bounded area and the corners: (0,0) (0,1) (1,0) and (1,1). Inside this bounded area: There are infinite number of places. (0, 0.00001) (0, 0.00001) (0, 0.001) ect. I want to have...

Hi everyone. I am working on a model which basically assigns the people to the places. The coordinates of the places are defined by me, there are 10 places. Instead of this, I want to define a square which has four corners. All points both inside and border of the square are candidate places for ass...

Hi everyone. I am using LibreOffice instead of Microsoft Office Excell, for some reasons. How can i upload data from LibreOffice to my gams model? Normally I am using below code but this is not working anymore. parameter a(i) people of i / $call xls2gms r=a2:b10 i=excel_name.xlsx o=peoplex.inc $incl...

Hi, I am working on a multi objective problem and in every situation the model gave me the ** Infeasible solution. Reduced gradient less than tolerance. error. Normally the model can solved as a single objective problem ( if I sum up two objective function in a row). But when I try to split the obje...

Got it but is there any chance to see the input codes as lingo codes?
