Very interesting. Is there any hint as to how much LocalSolver costs? If they're doing 3 minute runs for major optimisation jobs for massive companies on a single server, I imagine the "contact us for pricing" should give me a hint that it's quite a lot.
From memory I believe their competition (gurobi etc) would charge somewhere in the range of $10k-$100k per year for a server, perhaps toward the upper end of the scale if the server is used to solve problems for a number of clients. I haven't paid attention to pricing for this for a few years.
