Refinement-based Construction of Correct Distributed Algorithms

Web1 de jan. de 2015 · 2.3 Challenge: Minimum Spanning Tree Problem. The minimum spanning tree (MST) problem has optimal substructure. The algorithm of Gallager, Humblet and Spira (GHS) [] is a well-known, difficult distributed algorithm that computes an MST for an injectively weighted network graph.We aim to find a certifying variant of the GHS. WebIn a recent distributed algorithm for this purpose, each processor maintains a delayed view of the pending work, which is represented in terms of points in virtual time. This paper presents a formal speci cation of that algorithm in the temporal logic TLA, and describes a mechanically veri ed correctness proof of its main properties. 1 Introduction little cougars daycare
