Max-plus objects to study the complexity of graphs

Probability 2011-11-09 v2 Combinatorics

Abstract

Given an undirected graph GG, we define a new object HGH_G, called the mp-chart of GG, in the max-plus algebra. We use it, together with the max-plus permanent, to describe the complexity of graphs. We show how to compute the mean and the variance of HGH_G in terms of the adjacency matrix of GG and we give a central limit theorem for HGH_G. Finally, we show that the mp-chart is easily tractable also for the complement graph.
