WebAdditional Resource. Sometimes, in problems, it is required to construct a state graph out of the given graphs and then, apply any standard algorithm, to solve the problem. This technique is known as Graph Modelling. Refer this blog for more about it and some solved example problems. Edit this page. Web12 apr 2024 · No, we cannot use union-find to detect cycles in a directed graph. This is because a directed graph cannot be represented using the disjoint-set (the data structure on which union-find is performed). When we say 'a union b' we cannot make out the direction of edge is a going to b? (or) is b going to a?

WebAlgorithm of Kruskal's. For any graph, G= (V,E) G = (V,E), finding an MST using Kruskal's algorithm involves the following steps -. Sort all the edges of the graph in ascending order of their weights. Check the edge with minimum weight, if including it in the answer forms a cycle discard it, otherwise include it in the answer.
