WebMar 28, 2024 · Independent set is a set of vertices such that any two vertices in the set do not have a direct edge between them. Maximal independent set is an independent set having highest number of vertices. Note: There can be more than one independent and maximal independent sets for a given graph. Examples: Input: V = 3, E = 0. 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. ipratropium how to say
