WebGiven an adjacency matrix, is there a way to determine if the graph will be a tree or a graph (whether or not there is a cycle). For example, given the adjacency matrix: This is not a tree since there is a cycle between Vertex 1, Vertex 2 and Vertex 4. Whereas given the adjacency matrix: This is a WebThe disadvantage of graph search is that it uses more memory (which we may or may not have) than tree search. This matters because graph search actually has exponential memory requirements in the worst case, making it impractical without either a really good search heuristic or an extremely simple problem. So, there is a trade-off between space ...
