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 … Here is an important landmark of greedy algorithms: 1. Greedy algorithms were conceptualized for many graph walk algorithms in the 1950s. 2. Esdger Djikstra conceptualized the algorithm to generate minimal spanning trees. He aimed to shorten the span of routes within the Dutch capital, Amsterdam. 3. … See more Logic in its easiest form was boiled down to “greedy” or “not greedy”.
