NettetDepth First Search. In Depth First Search, the node which was discovered the latest is expanded next i.e. the node which joined the frontier later, is expanded later. To achieve this, Depth First Search Algorithm uses a LIFO(Last In First Out) Queue. The following graph is explored by a Depth First Search Algorithm with 'A' as the initial node.

Nettet7. apr. 2016 · The space complexity is O (bm), i.e. space linear in length of action sequence! Need only store a single path from the root to the leaf node, along with remaining unexpanded sibling nodes for each node on path. Another answer on StackOverflow states that it is O (n + m). algorithm. time-complexity. NettetDepth-first search An alternative algorithm for topological sorting is based on depth-first search . The algorithm loops through each node of the graph, in an arbitrary order, initiating a depth-first search that terminates when it hits any node that has already been visited since the beginning of the topological sort or the node has no outgoing edges …
