anyone knows if I can use the solver CLP in my problem modeled in PyOMO? I found only informations about the old version of pyomo where this was not possible. I'd like to know if it still impossible to use them together. Thanks in advance.
Pyomo is able to use the CBC solver through the AMPL solver library interface. The default linear solver in CBC is CLP. You could go that route.
Upshot: if you call the CBC solver from Pyomo with a linear model, it should be solved using CLP.
