## Abstract Given a text tree __t__ and a pattern tree __p__, tree pattern matching involves finding subtrees of __t__ which match __p.__ This paper proposed a parallel algorithm for tree pattern matching. The algorithm is designed to run in __O__(log __n__) parallel time using __mn__/log__n__ proc
We present a simple and implementable algorithm that computes a minimum spanning tree of an undirected weighted graph \(G=(V, E)\) of \(n=|V|\) vertices and \(m=|E|\) edges on an EREW PRAM in \(O\left(\log ^{3 / 2} n\right)\) time using \(n+m\) processors. This represents a substantial improvement i
