free download

Abstract. We construct a readable, compact and efficient implementation of Dijkstra's shortest path algorithm and Fibonacci heaps using Constraint Handling Rules (CHR), which is increasingly used as a high-level rule-based general-purpose programming language. In this paper we propose a natural straight forward implementation of Dijkstra's shortest path algorithm on a model of associative parallel processors of the SIMD type with bit-serial (or vertical) processing (the STAR-machine). In addition, we show how to extend this
