WebNov 1, 2010 · The element a[i] is the size of the maximal independent set in the subtree rooted in i which contains i. The element b[i] is the size of the maximal independent set in the subtree rooted in i which doesn't contain i. The algorithm computes these recursively, and then chooses the maximal of the two at the root.

WebApr 6, 2013 · A graph is well-covered if the independent domination number is equal to the independence number. Equivalently, every maximal independent set is a maximum independent set of the graph. For example, the balanced complete bipartite graphs are well-covered. The concept of well-covered graphs was introduced by Plummer [95]. WebNov 18, 2013 · Typical way to find independent sets is to consider the complement of a graph. A complement of a graph is defined as a graph with the same set of vertices and an edge between a pair if and only if there is no edge between them in the original graph. An independent set in the graph corresponds to a clique in the complements. how do mutagens produce mutationsWebJun 3, 2010 · 5. Yes, by definition, a maximal indpendent set is an independent set to which no more vertices can be added without violating the 'independence' condition. So just picking vertices till you can pick no more would give you a maximal independent set, can be done in linear time (i.e. linear in V + E ).
