WebJan 31, 2024 · This is because the code iterates through all the vertices in the graph once and checks if the size of the vector associated with each vertex is equal to 1. Space complexity : O(n) as the code uses a map to store the graph, where each vertex is a key and the value is a vector containing its adjacent vertices. The size of the map is directly ... WebMaybe a good way to look at it is the adjacency matrix. In a regular graph, every row-sum is equal. In the stronger property I'm speculating about, perhaps every row is a rotation of every other? My reason for interest in this is in the context of genetic algorithms. Often the search space is a regular graph (eg if the search space is a space ...
WebMay 2, 2016 · In graph theory, a bridge, isthmus, cut-edge, or cut arc is an edge of a graph whose deletion increases its number of connected components. See the Wikipedia article related to cut edge.
