Selection of Maximal Independent Set(MIS) using Breadth First Search • In graph theory, an independent set(IS) is a subset of vertices in a graph, such that no two vertex in IS are adjacent. • A maximal independent set is an independent set such that adding any other vertex to the set forces the set to contain an edge. • Select a MIS induced by a BFS ordering with respect to root node
