JSR331 v. 2.1.0 includes a new implementation of the linear solver “JSR331 CLP”. It’s based on the COIN CLP release 1.16.10 and uses a linear programming library “clp-java” developed by Dr. Nils Loehndorf from Quantego. This library allowed JSR331 to use CLP directly from Maven without any additional installation of the COIN CLP itself. However, CLP handles only real variables but not MIP.
A new open source product Rule Solver uses JSR331 as a foundation for building optimization decision services incorporated into business decision models.
