Greedy problems and its complexity
WebKruskal's algorithm is an example of a "greedy" algorithm, which means that it makes the locally optimal choice at each step. Specifically, it adds the next smallest edge to the tree that doesn't create a cycle. This approach has been proven to work for finding the minimum spanning tree of a graph. Kruskal's algorithm uses a data structure called a disjoint-set to … WebThe time complexity of greedy algorithms is generally less which means that greedy algorithms are usually fast. Greedy algorithms are used to find the optimal solution, …
