WebApr 10, 2024 · An independent set is defined as a set of nodes, such that there exists no edges between any 2 elements in the set. My first guess was a proof by contradiction. I assumed there is no cycle of length ⌈ n ⌉ and tried to prove there must exist a independent set, and vice versa. However, both approaches yielded no results.

It has been dubbed the Fibonacci number of a graph [] due to the fact that the number of independent sets in a path is always a Fibonacci number, and is now known as Merrifield–Simmons index in mathematical chemistry in honour of the work of chemists …
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
