Ha I just started the course in MiniZinc on Coursera and it is very nice and creative. One tidbit for someone with a mostly econometrics background that (for me, a starter in the language with some exposure to linear optimization in the past) it was hard getting it to perform operations that use floats. For me that took away most toy problems I am interested in. But it’s blazing fast for complex discrete optimization and very forgiving in the language, so at least it’s a great learn.
- hakank 4y agoConstraint programming solvers tends to focus on finite domain (integers) but there are some solvers that has some supports for floats as decision variables. You can try some of these solvers. For non linear models: * Gecode (included in the MiniZincIDE distribtion) * JaCoP (https://github.com/radsz/jacop https://github.com/radsz/jacop) * OptiMathSAT (https://optimathsat.disi.unitn.it/pages/fznreference.html https://optimathsat.disi.unitn.it/pages/fznreference.html) For linear models: * CBC (included in the MiniZincIDE distribution)
