Webof C , and the largest eigenvalue is often called the index. The spectrum of signed graphs has been studied by many authors, for instance see Akbari et al. (2024), Belardo and … WebFor a graph, a maximum cut is a cut whose size is at least the size of any other cut. That is, it is a partition of the graph's vertices into two complementary sets S and T, such that the number of edges between S and T is as large as possible. Finding such a cut is known as the max-cut problem.. The problem can be stated simply as follows. One wants a subset S of …

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.
