Graph entropy: a survey
WebThe definition that I have is that given a graph G, H ( G) = min X, Y I ( X; Y), where X is a uniformly random vertex in G and Y is an independent set containing X. Also, I ( X; Y) is the mutual information between X and Y defined by: I ( X; Y) = H ( X) − H ( X Y), where H is the regular entropy function. Webabove) where entropy can be applied fruitfully. In Section 3.2, we study entropy in the context of graph covering problems. A useful tool in this study is graph entropy discov-ered by K¨orner [18]. In fact, there are several equivalent definitions of graph entropy. We
