GAMS

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:

--- Generating LP model b1
--- blend.gms(55) 4 Mb
---   4 rows  10 columns  37 non-zeroes

Listing:

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_ModelSolve.html?search=numvar#UG_ModelSolve_ModelAttributesUsedAfterSolve. Some of them give you some size information on the just generated and solved model.
