Re: [rules-users] What's the difference between Drools and other constraints solvers?

My 2 cents on some side aspects of this debate (which I leave to Geoffrey :)) Most LP solvers are written in C/C++, which is great for efficiency but also a limitation on portability and platform (in)dependence. Provided that you find a version of the code that compiles in your specific environment. There are a couple of java interfaces (e.g. GLPK), but they do not solve the problem. I run a linux-64 ubuntu machine and had a VERY HARD time last time I tried ( ~1 year ago ) Choco is written in java and has a very permissive license model, unlike the others which are either commercial or GPLx, but the last time I tried it ( ~6 months ago ) it was still suffering from some numerical computation problems. I had it almost stuck in a local plateau for several seconds while trying to solve a small minimization problem with ~4 variables and ~10 constraints. @Geoffrey: but can Planner be used effectively - i.e. with little overhead - for LP optimization problems, including the integer-LP and the mixed-LP variants? And quadratic ones? -- View this message in context: http://drools.46999.n3.nabble.com/What-s-the-difference-between-Drools-an... Sent from the Drools: User forum mailing list archive at Nabble.com.
