hello every one
I’m using couenne to solve my problem, but my model is not supported by this solver.
the solver status is “6: capability problems” and it says:
“Gams function code 7 not supported”
“Error in setting up problem for coennne”
is there any way to understand which part of my model is not supported by couenne?
thanks a lot

Hi,
GAMS function code 7 is the “min”-operator. Somewhere in your model you must use the min-function, which is not supported by Couenne.
(With a recent GAMS version, you should get the word “min” instead of code 7.)

thanks a lot stephen. you’re right. I’ve used
“min"function in my constraints. I think, I should remove " min” function or I have to change my solver. do you know any other solver I can use to solve my minlp model instead of couenne?

From the global solvers, only SCIP and LINDO support the min-function so far.
You might want to reformulate with a binary variable or so if you want to stick with Couenne.
