I thought about the problem of determing |G(n)||G(n)|, when the values of |Gc(k)||Gc(k)| are known for k=1…nk=1…n. All families I am looking at have the nice property, that the connected components of a graph g∈Gg∈G are also in GG. The f...

number ofconnected components in a graphproblem. The idea is to startBreadth–first search (BFS)from each unprocessed node and increment the island count. Each BFS traversal will mark all cells which make one island as processed. So, the problem reduces to finding the total number of BFS ...
You are given a connected undirected graph of n nodes and m edges and an integer k. Now the question is, What is the maximum number of connected components you can create by deleting exactly k edges (k <= m)? Addition: How to solve the problem if there are Q queries of k?
