You could defined two mutually recursive functions on the set of rooted trees: f (T) = number of independent sets containing the … WebThe only independent sets are sets of only rows or sets of only columns, and each of them can be dominated by a single vertex (a column or a row), so iγ(G) = 1. However, to dominate all vertices we need at least one row and one column, so γ(G) = 2. Moreover, the ratio between γ(G) / iγ(G) can be arbitrarily large.

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. 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.

WebIn a simple graph (one without loops or multiple edges) a singleton vertex is always vacuously both a clique and an independent set, for exactly the reasons that you give. As Gerry Myerson noted in his comment, a singleton vertex need not be an independent set if you allow your graph to contain loops, but it will still be a clique.
