ECLiPSe Constraint Logic Programming System Version 7.1

The ECLiPSe Constraint Logic Programming System 7.1, released by Coninfer Ltd as build #13, is an open-source platform designed for the rapid, cost-effective creation and deployment of constraint programming solutions. Rooted in the Prolog tradition, it equips operations-research professionals, software engineers, and educators with a unified environment for modelling and solving hard combinatorial problems encountered in planning, scheduling, resource allocation, timetabling, transport optimisation, and related domains. Its extensible architecture bundles several high-performance constraint solver libraries, a declarative high-level modelling and control language, ready-made interfaces to external mathematical-programming engines, an integrated development environment for interactive experimentation, and embeddable APIs that allow the engine to be hosted inside larger applications. Because the system exposes the entire constraint-programming pipeline—from problem encoding through custom search strategies to solution visualisation—it is equally suited for production use and for teaching key aspects of combinatorial optimisation such as problem abstraction, constraint modelling, search design, and hybrid algorithms. The current stable line is represented by version 7.1, and only one major release stream is maintained, ensuring that users always work with the latest refinements in solver technology and language features. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
