WebThe Union-Find algorithm divides the vertices into clusters and allows us to check if two vertices belong to the same cluster or not and hence decide whether adding an edge creates a cycle. ...

Webunion(person P1, person P2){ fst_leader = find_leader_of(P!) snd_leader = find_leader_of(P2) parent[snd_leader] = fst_leader } there are other approaches to improve union-find and other ways to choose who will be leader of who, but this is the basics you must understand in order to know what union-find is about.

We first find the maximum deadline of all jobs. Let the max deadline be m. We create m+1 individual sets. If a job is assigned a time slot of t where t >= 0, then the job is scheduled during [t-1, t]. So a set with value X represents the time slot [X-1, X].
WebDec 22, 2024 · Union-Find Algorithm can be used to check whether an undirected graph contains cycle or not. Note that we have discussed an algorithm to detect cycle. This is another method based on Union-Find. This method assumes that the graph doesn\’t contain any self-loops. We can keep track of the subsets in a 1D array, let\’s call it parent[].
