Some common algorithms

1, A * search algorithm-graphical search algorithm, from a given point of origin to a given endpoint to calculate the path. A heuristic estimate is used to estimate the optimal path through the node for each node and to prioritize each location. The algorithm accesses these nodes in the order in which they are obtained. Therefore, A * search algorithm is an example of a best-case-first search.2, Cluster search (aka Directed Search, Beam Search)--optim
