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 that is understood by a wide range of solvers.
We have developed an extensive online course! Head over to Coursera's Basic Modeling for Discrete Optimization and Advanced Modeling for Discrete Optimization courses for an in-depth introduction to constraint modeling using MiniZinc.
The book Building Decision Support Systems using MiniZinc by Mark Wallace introduces readers to the principles of intelligent decision support systems (IDSS) and how to build them with MiniZinc.
