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 $H_G$ in terms of the adjacency matrix of $G$ and we give a central limit theorem for $H_G$. Finally, we show that the mp-chart is easily tractable also for the complement graph.", "revisions": [ { "version": "v2", "updated": "2011-11-08T10:16:25.000Z" } ], "analyses": { "subjects": [ "05C30", "60F05" ], "keywords": [ "max-plus objects", "complexity", "central limit theorem", "complement graph", "max-plus algebra" ], "note": { "typesetting": "TeX", "pages": 16, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1111.1352B" } } }
