WebFeb 19, 2015 · The recursive best-first search (RBFS) algorithm is a simple recursive algorithm that attempts to mimic the operation of A-star search (i.e., the standard best-first search with an evaluation function that adds up the path cost and the heuristic), but using only linear space (instead of showing an exponential space complexity). WebExplanation: Create a graph. Initialize a starting node. Send the graph and initial node as parameters to the bfs function. Mark the initial node as visited and push it into the queue. Explore the initial node and add its neighbours to the queue and remove the initial node from the queue. Check if the neighbours node of a neighbouring node is ...
