In-house testing of CPLEX distributed MIP

Distributed optimization is now part of standard CPLEX releases. In fact, it’s been there since release 12.5. I decided to do some experiments and post on this after seeing Daniel Junglas’ talk at the German OR Conference in September, but writing the post has been delayed until recently. I summarize the results of my experiments and compare those […]

In-house testing of the Gurobi 6 distributed MIP [dual]

Distributed optimization is now part of the Gurobi 6.0 release. In today’s post, I talk about some tests I ran with the distributed MIP algorithm. The associated primal post discusses results presented by Gurobi at the INFORMS 2014 Annual conference.  Don’t worry, the next set of posts will cover the same topic, this time with CPLEX. Overall, it […]

Distributed MIP solving reaches Gurobi [primal]

Distributed optimization has now reached the point where it is incorporated into general-purpose mixed-integer programming (MIP) solvers such as CPLEX and Gurobi. In today’s post, I will summarize the implications of some results presented at the INFORMS 2014 annual conference by Dr. Ed Rothberg. You can see the full slide deck here. The associated dual post presents some of […]
