I’m pretty new to the world of OR and SCIP and I’m having some trouble understanding the Subscip idea in SCIP or the example I’m referring to. I have a complex 2D cutting stock problem and I’m trying to use and understand the Branch And Price Bin Packing example on the SCIP website (https://scipopt.org/scip/doc/html/BINPACKING_MAIN.php).

I am looking for a sensible alternative to commercial LP solvers like CPLEX and GUROBI.

I’ve followed the steps on the documentation for macOS but looks like my Java environment is unable to detect scip.
