Some Upper Bounds for the Net Laplacian Index of a Signed Graph. Bulletin of the Iranian Mathematical Society, Vol. 48, Issue. 1, p. 243. CrossRef; WebIn this paper we introduce the notion of best swap for a failing edge of a single source shortest paths tree (SPT) S (r) rooted in r in a weighted graph G=(V, E). Given an edge e∈ S (r), an edge e¢ Î E {e e'∈ E \\ left {e\ right\} is a swap edge if the swap tree S e\ e¢(r) S_ e \ e'\ left (r\ right) obtained by swapping e with e′ in S (r) is a spanning tree of G.

WebFeb 27, 2003 · We propose a new linear time algorithm to represent a planar graph. Based on a specific triangulation of the graph, our coding takes on average 5.03 bits per node, and 3.37 bits per node if the graph is maximal. We derive from this representation that the number of unlabeled planar graphs with n nodes is at most 2 n + O (log n ), where 5.
