Generic Constraint Development Environment

Derivative-Free Global Optimization Algorithm (C++, Python binding) - Continuous, Discrete, TSP, NLS, MINLP

Codac (Catalog Of Domains And Contractors) is a C++/Python/Matlab library providing tools for interval computations and constraint programming over real numbers, trajectories and sets. It has numerous applications in parameter estimation, guaranteed integration, robot localization, and provides reliable outputs.

NACRE : Nogood And Clause Reasoning Engine

This repository introduces two novel CP approaches for mining closed interval patterns directly from numerical datasets. Unlike existing methods that require pre- and post-processing steps to handle numerical data, our models perform pattern mining seamlessly, preserving information integrity.
