Constraints Reactor

An engine for evaluating constraint rules.

Written in Kotlin and Java.

Build Status

This is an implementation of the Constraint Handling Rules semantics with custom extensions, influenced by JCHR.

The main features are built-in support for terms as the data structure, including terms unification, and logical variables.

The use of terms as constraint parameters enables to implement optimizations for handling multi-head rules. Also, this implementation relies heavily on term unification when matching rules.

Logical variables enable to pass parameters to constraints as indirect references, which may be assigned later. Assigning a value to an unbound logical variable reactivates the constraint in which it serves as a parameter. Two logical variables may be joined to be treated as one.

NOTE: this implementation does not include support for parsing the CHR syntax.
