iterative deepening         
<algorithm> A graph search algorithm that will find the shortest path with some given property, even when the graph contains cycles. When searching for a path through a graph, starting at a given initial node, where the path (or its end node) has some desired property, a depth-first search may never find a solution if it enters a cycle in the graph. Rather than avoiding cycles (i.e. never extend a path with a node it already contains), iterative deepening explores all paths up to length (or "depth") N, starting from N=0 and increasing N until a solution is found.

Iterative deepening A*         
HEURISTIC PATHFINDING ALGORITHM
IDA*
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 evaluate the remaining cost to get to the goal from the A* search algorithm.
Iterative method         
NUMERICAL METHOD IN WHICH THE N-TH APPROXIMATION OF THE SOLUTION IS OBTAINED ON THE BASIS ON THE (N-1) PREVIOUS APPROXIMATIONS
Iterative methods; Krylov subspace methods; Krylov subspace method; Iterative approximation; Iteration scheme; Iterative algorithm; Iterative procedure; Iteration algorithm; Iteration methods; Iterative convergence; Iterative solver; Direct method (computational mathematics); Stationary iterative method; Iteration method
In computational mathematics, an iterative method is a mathematical procedure that uses an initial value to generate a sequence of improving approximate solutions for a class of problems, in which the n-th approximation is derived from the previous ones. A specific implementation of an iterative method, including the termination criteria, is an algorithm of the iterative method.

Iterative deepening depth-first search

In computer science, iterative deepening search or more specifically iterative deepening depth-first search (IDS or IDDFS) is a state space/graph search strategy in which a depth-limited version of depth-first search is run repeatedly with increasing depth limits until the goal is found. IDDFS is optimal like breadth-first search, but uses much less memory; at each iteration, it visits the nodes in the search tree in the same order as depth-first search, but the cumulative order in which nodes are first visited is effectively breadth-first.
