WebWhat is the time complexity of Prim’s algorithm on an input graph with N edges? The time complexity of Prim’s algorithm using the adjacency matrix of a complete graph is Theta(n^2). We can see this from the pseudocode of Prim’s algorithm with our adjacency matrix H : Initialize a set Q of vertices not in the tree, initially all vertices. WebTime Complexity Analysis of Kruskal's Algorithm. In practice, while implementing Kruskal's algorithm, we keep track of all the edges using subsets. Using multiple subsets helps us to avoid cycles in our final MST output. For this purpose, we make use of a data structure called Disjoint Sets or union-find.
