Web19 mar 2024 · Every undirected graph can be represented as a directed graph by replacing every edge (i,j) with 2 edges (i,j);(j, i). And if we are running Floyd–Warshall algorithm on such a directed graph - it would work correctly, as always. The algorithm works correctly for both directed and undirected graphs.

Web28 mar 2024 · To detect the cycles in an undirected graph, we started with a Depth-first search traversal of the graph. We maintain an array of all the visited vertices, and during the traversal, whenever we get an edge that goes back to an already visited vertex, also known as a back edge. We return the answer that the graph is cyclic.

Web8 giu 2024 · We will implement the DSU of the 2-edge-connected components without the Union by rank optimization, therefore we will get the complexity O ( log n) on average per query. To achieve the complexity O ( 1) on average per query, we need to combine the vertices of the cycle according to Union by rank, and then assign par [] accordingly. … Web15 ago 2024 · It follows that r ( G) = 0 iff G is a forest, i.e. G has no cycles. Now consider what happens when you remove an edge from a graph G. If that edge is part of a cycle, you decrease E by 1 but do not change V or c, so r ( G) decreases by 1. If the edge is not part of a cycle, you additionally increase c by 1 (since you split a component ...
