Parametric strategies using grasshopper by arturo tedeschi author. Then find the next unmarked vertex ti, find all the yetunmarked nodes reachable from there, and label them as belonging to equivalence class ti. Any sequence of k union operations on a collection of n items takes time at most proportional to k log k. Since the nth fibonacci number is at most n bits, it is reasonable to look for a faster algorithm. After k unions, at most 2k items have been involved in a union. The above union and find are naive and the worst case time complexity is linear. If p is connected to q, then q is connected to p transitive.
