Spletalmost shortest cycle (a cycle whose length exceeds the length of a shortest cycle by at most 1) in an undirected graph can be found in O(V2) time. Monien [6] described a sophisticated O(V2 (V)) algorithm for nding shortest even length cycles (SELCs) in undirected graphs, where (n)= (n;n) is the func-tional inverse of Ackermann’s function. Splet08. okt. 2024 · We translate the undirected graph into its directed version (replace each undirected each by two directed edges being inverse to each other) and use Suurballe‘s …
SpletYou are given a connected, undirected graph with ‘V’ vertices and ‘E’ edges. You are provided with two vertices, ‘src’ and ‘dest’. Your task is to return the shortest distance between the given vertices ‘src’ and ‘dest’. For Example: For the given graph, The shortest distance between 1 and 3 is 2 (via 1 <-> 2 <-> 3). SpletIn graph theory, the girthof an undirected graphis the length of a shortest cyclecontained in the graph.[1] If the graph does not contain any cycles (that is, it is a forest), its girth is defined to be infinity.[2] For example, a 4-cycle (square) has girth 4. A grid has girth 4 as well, and a triangular mesh has girth 3.
