On the independence number of sparse graphs
WebOur proof technique is an extension of a method of Caro [New Results on the Independence Number, Technical report, Tel Aviv University, 1979] and Wei [A Lower Bound on the Stability Number of a Simple Graph, TM 81-11217-9, Bell Laboratories, Berkley Heights, NJ, 1981], and we also give a new short proof of the main result of Caro … Web8 de abr. de 2014 · 2 Answers. Generally, it is said that a graph with n vertices is dense if it has Theta ( n ^2) edges and is sparse otherwise. This means that a graph is dense if the average degree of each vertex is lineal, and sparse if sublineal. Sparsity does not deppend on size. For instance, trees are sparse (because a tree with n nodes has n-1 edges).

WebOne simple and efficient way to precompute this table is by observing that one interval whose length is a power of 2 can be split into 2 smaller intervals. This observation translates into the following recurrence relation: r m q [ h] [ i] = m i n ( r m q [ h − 1] [ i], r m q [ h − 1] [ i + 2 h − 1]) . Below is an example of one such ...

Webbound on the independence number of Kr-free graphs for large values of r. We also show how to obtain an algorithmic version of the above-mentioned SA+-based integrality gap result, via a coloring algorithm of Johansson. The resulting approximation guarantee of Oe(d/log2d) matches the best unique-games-based hardness result up to lower-
Web26 de set. de 2012 · As the names indicate sparse graphs are sparsely connected (eg: Trees). Usually the number of edges is in O (n) where n is the number of vertices. Therefore adjacency lists are preferred since they require constant space for every edge. Dense graphs are densely connected. Here number of edges is usually O (n^2).
