Constraint Handling Rules (CHR) is a high-level programming language based on
multiheaded multiset rewrite rules. Originally designed for writing user-defined constraint …

Constraint Handling Rules (CHR) is a high-level rule-based programming language which
is increasingly used for general-purpose programming. We introduce the CHR machine, a …

We construct a readable, compact and efficient implementation of Dijkstra's shortest path
algorithm and Fibonacci heaps using Constraint Handling Rules (CHR), which is …

This paper introduces CHRrp: Constraint Handling Rules with user-definable rule priorities.
CHRrp offers flexible execution control which is lacking in CHR. A formal operational …

This article introduces CHR++, an implementation of CHR (Constraint Handling Rules) in
C++. CHR++ has been designed to be efficient, user-friendly, and to make it easier to model …

Thirty years after Forgy's seminal dissertation, Rete remains the de facto standard matching
algorithm. Despite promising research results, alternative algorithms such as TREAT and …

Constraint Handling Rules (CHR)[11, 17] is a high-level programming language extension
based on multi-headed committed-choice rules. CHR is constraintdriven: adding constraints …

CHR is usually compiled to high-level languages (like Prolog) that make it hard or
impossible to express low-level optimizations. This is a pity, because it confines CHR to be a …

In this paper, we address the different conceptual and technical difficulties encountered
when embedding CHR into an imperative host language. We argue that a tight, natural …

This paper introduces a framework for the specification of tree search strategies in CHR with
disjunction (CHR∨). We support the specification of common search strategies such as …
