New release of MiniZinc

Posted on December 13, 2019 by decisionmanagementcommunity

MiniZinc is a free and open-source constraint modeling language. You can use MiniZinc to model constraint satisfaction and optimization problems in a high-level, solver-independent way, taking advantage of a large library of pre-defined constraints. Your model is then compiled into FlatZinc, a solver input language … Continue reading →
