I hope this isn’t a dumb question…

With the precedent version of JuMP, to define the kind of optimization problem (LP, MIP,…), the syntax was

Model(solver=GLPKSolverMIP(args…))

or

Model(solver=GLPKSolverLP())

I read in the documentation that now the syntax is :

Model(with_optimizer(GLPK.Optimizer, args…))

So I don’t understand where to define the kind of optimization problem… I trie several tests but didn’t find out…

I you can enlighten me !

Thanks
