tests/test-gamslib-cuopt.pyandtests/baseline.txt.baseline.txt: 73 gamslib models (LP/MIP/QCP) that CPLEX solves to proven optimality (optcr=0) within 60 s in a single solve, with the CPLEX objective value.gamslib, solves it withsolver=cuopt(reslim=120by default), reads the objective from the trace file and fails if|obj-ref|/max(1,|ref|)exceeds--rtol(default 1e-6). Exits 1 on any mismatch or failure.Excluded from the baseline: BCH models (require CPLEX), bidsos (SOS2 unsupported), badmip (cuOpt integrality tolerance 1e-5 trips the model's exact check), and clad/mws/nurses (cuOpt cannot close the gap within the time limit).
