The problems we solve (and the timeframe we're under) are among the hardest in the OR sector. Not using CPLEX or GUROBI isn't an option.

GUROBI has some benchmarks on their site that are illuminating.

Gurobi also got caught cheating in some benchmarks and were pulled from them. It's a shame, because they really are the fastest in most tests.

What are the constraint matrix dimensions and density of the matrix, objective and right hand sides? Can you email me at [e-mail] ?
