G-28. Shortest Path in Undirected Graph with Unit Weights

SpletThe shortest path problem is about finding a path between 2 vertices in a graph such that the total sum of the edges weights is minimum. This problem could be solved easily using (BFS) if all edge weights were ( 1 ), but here weights can take any value. Three different algorithms are discussed below depending on the use-case.

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.

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.
