2. Iterative deepening A* - Wikipedia

   en.wikipedia.org/wiki/Iterative_deepening_A*

   Iterative deepening A* (IDA*) is a graph traversal and path search algorithm that can find the shortest path between a designated start node and any member of a set of goal nodes in a weighted graph. It is a variant of iterative deepening depth-first search that borrows the idea to use a heuristic function to conservatively estimate the ...
