This paper presents an algorithm for recognizing two dimensional partial orders. The algorithm accepts as input an arbitrary partial order G and responds “yes” if the dimension of G is less than or equal to two and responds “no” otherwise. As part of the recognition process, the algorithm decomposes the partial order in a canonical way which can be used to determine whether two partial orders of dimension...
A model of VLSI computation suitable for the description of algorithms at a high level is introduced. The model is basically a language to express parallel computations which can be efficiently implemented by a VLSI circuit. This language is used to describe area-time efficient algorithms for a few well known graph problems. The exact complexity of these algorithms and their relevance to recent work...
