Kruskal’s algorithm may have disconnected graphs. … WebMay 15, 2024 · The time complexity of the Union-Find algorithm is O(log n) for each edge in the graph. The time complexity of Kruskal’s algorithm is O(m log n), where m is the number of edges and n is the number of vertices in the graph. This is because the edges must be sorted before the algorithm can begin, and this sorting step takes O(m log n) time.

Complexity of prims and kruskal

WebThe time complexity is O(VlogV + ElogV) = O(ElogV), making it the same as Kruskal's algorithm. However, Prim's algorithm can be improved using Fibonacci Heaps (cf Cormen) to O(E + logV). Key terms: Predecessor list A data structure for defining a graph by storing a predecessor for each node with that node. WebFeb 4, 2024 · The Time Complexity of Prim’s algorithm is O(n2). The algorithm spends most of the time in finding the smallest edge. So time of the algorithm basically depends on how do we search this edge.
