If you haven’t already heard (e.g., through this blog post or this one), Gurobi 1.1 is now available. You can download a free trial version from Gurobi’s website. The trial version is valid for 6 months and it includes all solvers but has restrictions on problem size (500 variables and 500 constraints).
I was curious to see their pricing. There are different options but just to give you an idea, for academic licenses (strictly forbidden for commercial use) a 1-year, 100 simultaneous-use floating license costs $2500 with a yearly renewal charge of $500. A perpetual single user, single machine license with unlimited use is $850.
I can’t wait to get my hands on Gurobi and try it out. Unfortunately it has to wait a little due to a very busy travel schedule in the next month.
