Hi everyone !
I have a MIP model in GAMS. ( model name is : TSmodel)
How I can find the number of variable( binary and continues variable ) and number of constraints in Model?
Thanks!

The GAMS Log and listing have this informations:
Log:
Code: Select all
--- Generating LP model b1
--- blend.gms(55) 4 Mb
--- 4 rows 10 columns 37 non-zeroes
Listing:
Code: Select all
MODEL STATISTICS
BLOCKS OF EQUATIONS 2 SINGLE EQUATIONS 4
BLOCKS OF VARIABLES 2 SINGLE VARIABLES 10
NON ZERO ELEMENTS 37
Inside GAMS you have access to the model suffixes e.g.
b1.numVar after the solve. Find the different model suffixes here:
https://www.gams.com/latest/docs/UG_Mod ... AfterSolve. Some of them give you some size information on the just generated and solved model.
