Webshowing that many of the vertex subsets of approximately that size are independent sets. Definition 1. Given a graph G, let i(G) denote the number of independent sets in G. Upper bounds for i(G) have been motivated by combinatorial group theory. In [2], Alon showed that if G is a d-regular graph, then i(G) ≤2(1/2+o(d))n; he also conjectured 2 WebOct 18, 2016 · If the problem has the property that the decision version can be converted to the search version, it is self reducibility. You can show that all NP-complete problems are self reducible.

In fact, sufficiently large graphs with no large cliques have large independent sets, a theme that is explored in Ramsey theory. A set is independent if and only if its complement is a vertex cover. Therefore, the sum of the size of the largest independent set and the size of a minimum vertex cover is equal to the number of …
