WebSep 22, 2024 · For graph theory, this means that one should study properties of graphs that are invariant under graph automorphisms. For example, permuting vertices (and adjusting the edges accordingly) should be irrelevant. That works nicely in theory, but causes friction for computation: we have to use data structures to represent graphs, and … WebBreadth-first search ( BFS) is an algorithm for searching a tree data structure for a node that satisfies a given property. It starts at the tree root and explores all nodes at the present depth prior to moving on to the nodes at the next depth level. Extra memory, usually a queue, is needed to keep track of the child nodes that were ...
