In this paper we prove that deciding whether a distributed system (represented as a coloured digraph with n nodes) has weak sense of direction is in AC^1 (using n^6 processors). Moreover, we show that deciding sense of direction is in P. Our algorithms can also be used to decide in AC^1 whether a coloured graph is a Cayley colour graph.

Abstract

In this paper we prove that deciding whether a distributed system (represented as a coloured digraph with n nodes) has weak sense of direction is in AC^1 (using n^6 processors). Moreover, we show that deciding sense of direction is in P. Our algorithms can also be used to decide in AC^1 whether a coloured graph is a Cayley colour graph.
