Web4 dec. 2012 · igraph is a library for “complex network research”. While it integrates very well with R and provides a lot of convenient functions, huge graphs put a quick end to all the joy. The good news is: not all functions in igraph have bad performance. Some are actually amazingly fast – one just needs to avoid the bad ones. WebIn mathematics and computer science, connectivity is one of the basic concepts of graph theory: it asks for the minimum number of elements (nodes or edges) that need to be removed to separate the remaining nodes into two or more isolated subgraphs. It is closely related to the theory of network flow problems.
