WebAbstract: Let m(G) denote the number of maximal independent sets of vertices in a graph G and let c(n,r) be the maximum value of m(G) over all connected graphs with n vertices and at most r cycles.

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. porsche taycan car dealer near hermosa beach
