University course: definitions, lecture notes, books, language descriptions, links.

Online tutorial/textbook for beginners to the area of constraint programming. This area is of the set of less known software technologies, but is evolving rapidly and has a growing, significant commercial interest.

Building a user-friendly Graphical User Interface (GUI) with languages like C++ or Java is difficult and time-consuming, because such languages demand specifying many details about the geometric data of layout, the sequence in which items are displaye...

Generic Constraint Development Environment. Constraint solver implemented as C++ library. Main goals: modifiability, extensibility, speed. Features: integer and set variables, large constraint set, copying-based search. [Open Source, BSD]

ResearchIndex: In the last 20 years, many algorithms and heuristics were developed to find solutions in constraint networks. Their number increased so much that it quickly became vital to compare performance to propose a small number of good methods.
