• Iterative (or incremental) development is what's meant by doing only a little bit of product development at a time so that you can learn from the work you've done. The idea is, the more quickly you can get your work into the hands of users, the quicker you can learn what works and what doesn't work.
• The next optimization was inspired by the Iterative Deepening Search. During the search in every iteration, we know exactly what was the best move in the previous iteration, so if we consider the best row from the previous iteration first, it is very possible that it will have a high alpha/beta value and more of the search tree will be pruned.
Iterative Deepening Search Iterative deepening does repeated depth-limited searches, starting with a limit of zero and incrementing once each time. As a result, it has the space-saving benefits of depth-first search, but is also complete and optimal, since it will visit all the nodes on the same level first before continuing on to the next ... In numerical analysis, hill climbing is a mathematical optimization technique which belongs to the family of local search.It is an iterative algorithm that starts with an arbitrary solution to a problem, then attempts to find a better solution by making an incremental change to the solution.
Performing the same search without remembering previously visited nodes results in visiting nodes in the order A, B, D, F, E, A, B, D, F, E, etc. forever, caught in the A, B, D, F, E cycle and never reaching C or G. Iterative deepening is one technique to avoid this infinite loop and would reach all nodes.

The iterative deepening algorithm fixes the limitations of having to settle for a fixed depth when a deeper search may come up with a better answer. In this video, discover how iterative deepening is suitable for coming up with the best solution possible in the limited time allotted.

• Based on the idea of the limited-depth search, but • It resolves the difficulty of knowing the depth limit ahead of time. Idea: try all depth limits in an increasing order. That is, search first with the depth limit l=0, then l=1, l=2, and so on until the solution is reached Iterative deepening combines advantages of the depth-first and This paper presents a modification to the BHFFA called Iterative Deepening Bi-directional Heuristic Front-to-Front Algorithm (IDBHFFA) that has been analyzed and implemented using the 8-puzzle problem. The proposed algorithm performs BHFFA in a number of iterations. For each iteration, two thresholds are maintained, one for each search frontier.
• NOTES ON ITERATIVE DEEPENING Revised by Charles Elkan, April 22, 2002 THE SEARCH PROBLEM We want to use a search algorithm to explore a space of possible solutions to a given problem. Each possible solution is called a node. If a node is a solution to the problem, then it is called a goal node.

• What Advantages and Disadvantages of V-Model, « What is Iterative Incremental Development Model? Creating system design as well as architecture. V model presentation 1. Both teams (test and development) work in parallel. The test team involves in reviewing the LLD and writes functional test plan and functional test cases.
Iterative-Deepening Search •IDS has advantages of –Breadth-first search –similar optimality and completeness guarantees –Depth-first search –Modest memory requirements •This is the preferred blind search method when the search space is largeand the solution depth is unknown •Many states are expanded multiple times be rewritten into a graph search – such as chess – can be solved by the computer. Alas, the computer will not become clever in the ordinary meaning of the word if we implement these algorithms, at best, it will be able to systematically examine a graph in search of a solution.

• All together, an iterative deepening search from depth all the way down to depth expands only about % more nodes than a single breadth-first or depth-limited search to depth , when =. [5] The higher the branching factor, the lower the overhead of repeatedly expanded states, [1] : 6 but even when the branching factor is 2, iterative deepening search only takes about twice as long as a complete breadth-first search.
