Picat is a programming language that integrates LP (Logic Programming), FP (Functional programming), scripting, CP (Constraint programming), and DP (Dynamic programming) with tabling. Picat incorporates many language features for better productivity of software development, including pattern-matching rules, explicit non-determinism, explicit unification, functions, constraints, and tabling. It is not rare to find problems for which Picat requires an order of magnitude fewer lines of code than many other languages.
