🔄 Changed
org.ojalgo.optimisation
- 🔄 Changed what alternatives (method signatures) are available to copy and/or relax optimisation models. These are API (behaviour) breaking changes, but of features primarily used within ojAlgo (when writing test cases and such). If you've used methods named
copy,relax,snapshotorsimplifyinExpressionsBasedModelthen be aware. Even if your code still compiles it may not do exactly what it did before. - 🔨 Refactoring of
ExpressionsBasedModelprimarily affecting how presolving deals with integer variables - increased the number of cases when integer rounding will actually occur.
🛠 Fixed
org.ojalgo.optimisation
- 🛠 Fixed problem with progress/debug logging of
IntegerSolver. The node id and count were not correct. (Only an issue with log output.)
