	WikiMiki.net - Tree search algorithm (Site not responding. Last check: 2007-09-17)
		Algorithms are often implemented in software, and advancing the state of the art in algorithms is responsible for many of the most spectacular successes in computing.
		The field of algorithms is highly formal and many things can be proved about a given algorithm (using complexity theory), including roughly how long it will take to complete, as compared to the size of its input (the number of options it must consider).
		A splay tree is a binary search tree that automatically moves frequently accessed elements nearer to the root.

	Search algorithm Summary
		One can be constructed simply by using a variant of the binary search algorithm, but the real challenge lies in inserting and deleting data from the binary search tree in such a way as to keep it balanced, in order to accommodate modifications in the database corresponding to the binary search tree.
		In computer science, a search algorithm, broadly speaking, is an algorithm that takes a problem as input and returns a solution to the problem, usually after evaluating a number of possible solutions.
		Brute-force search or "naïve"/uninformed search algorithms use the simplest, most intuitive method of searching through the search space, whereas informed search algorithms use heuristics to apply knowledge about the structure of the search space to try to reduce the amount of time spent searching.

	Computer Chess Programming » Blog Archive » Chess Tree Search
		The problem for most interesting games is that the size of this tree is tremendously huge, something like W^D, where W is the average number of moves per position and D is the depth of the tree, Searching the whole tree is impossible, mainly due to lack of time, even on the fastest computers.
		Chess tree search is an alternation between maximizing and minimizing the value of the positions in the tree; this is often abbreviated to minimaxing.
		The number of positions that has to be searched by this algorithm is W^D, where W is the width of the tree (average number of moves possible in each position) and D is the depth of the tree (^ indicates exponentiation).

		Tree search algorithms play an important role in many applications in the field of artificial intelligence.
		Thus, irrelevant variations of the tree are searched as deep as the important ones.
		Moreover, in the worst case the decision at the root of the tree is based on a single static evaluation at one leaf of the game tree searched.

		The resulting evaluation at the leaf nodes of the tree is the resulting evaluation for the branch of the original search.
		The advantage of this algorithm is that it uses a zero-window size for the alpha and beta parameters; what this provides is the most number of cut-offs and will search the minimum amount of the tree.
		Despite the algorithm being common and relatively simple, the challenge to create a parallel version is not as trivial as distributing the work evenly.

	Tree traversal - Wikipedia, the free encyclopedia
		In computer science, tree traversal is the process of visiting each node in a tree data structure exactly one time.
		The height of a nonempty tree is the maximum level of a node in the tree plus one.

		Buros ProbCut algorithm [12] uses shallow extra searches instead of deep searches for positions in a certain level of the tree which seem to be irrelevant for the decision at the root.
		Thus, irrelevant variations of the tree are searched as deep as the relevant ones.
		Last but not least, in the worst case the decision at the root of the tree is based on a single static evaluation at one leaf of the game tree searched.

	search
		Branching factor is a measure of the complexity of a position reached in the tree search which characterizes this complexity in terms of the average number of successor branches (legal moves) from this position.
		Search() simply tests to see if the current ply is a split point, and if so it copies the shared move list to the local move list, calls Select() to choose one for searching and then removes it from the move list.
		Another example is that the search extensions used by Cray Blitz at ply=N are affected by the extensions at plies before N in the tree.

	Tree Search (Site not responding. Last check: 2007-09-17)
		For this search to be efficient the lemmings must be grouped into equivalence classes, so that choosing only one lemming in the class is considered.
		The tree search, if that's what it is, is abstract, because the node in which there is a leftover blocker is at the end of the game.
		Tree search often becomes inefficient when the sequence of actions is divisible into actions that independently affect different aspects of the situation.

	Search Tree Introduction
		A search function is a function that is passed information about the game, and tries to find the best move for side that the program is playing.
		There are lots of ways to write a search function, and I don't want to stifle creativity by only talking about one of them, but I want these pages to focus on practical methods.
		So what is done instead is that the tree is searched as deeply as possible within a given time frame, and in those positions where you don't know how the game will end, you look at the position, take a guess, and assign a value to this position based upon the guess.

		The Binary search algorithm required a sorted list; if your data is unsorted (it may be changing dynamically in time, if you are updating a database of customers, for example), you can populate a tree which approximates a sorted list, and then use a modified search algorithm (binary tree search) to search the list.
		the element is unequal to a leaf of the binary search tree.
		In this case the binary search tree serves as the decision tree for the binary tree search algorithm.

		Many of the problems in Tree search can be solved using SQL type searches.
		In a Hierarchical search your path is forced by the branches of the tree (example name by alphabetical order) while with SQL you have the flexibility of accessing the data along multiple directions (name, address, income etc...).
		While SQL search offers great flexibility to search the data, it still operates like a computer does: by constraints.

	BioMed Central \| Full text \| A double classification tree search algorithm for index SNP selection
		We have re-formulated the index SNP selection problem and developed a new greedy algorithm for index SNP selection based on a double classification tree search algorithm similar to the double search algorithm we previously developed for physical mapping [6].
		Our algorithm can be divided into two phases: a greedy phase to choose the classifiers and a tree-building phase to divide the haplotype patterns into the subtrees.
		For the second round search, we force the last classifier of the first round to be used as the first classifier in the second round.

	Hans J. Berliner - Monday September 18, 1995 - Department of Computing Science, University of Alberta
		Since the 1940's when scientists first began examining how to search in computer games, it was clear that all proposals for "human-like" searches failed one crucial test.
		This algorithm was developed based on notions of what is undeniably true about human behavior, and how to implement this in a computer program.
		At present the B* search algorithm is used in the chess machine Hitech.

	A* search algorithm - Wikipedia, the free encyclopedia
		In computer science, A* (pronounced "A star") is a graph search algorithm that finds a path from a given initial node to a given goal node (or one passing a given goal test).
		The A* algorithm is therefore an example of best-first search.
		In their paper, it was called algorithm A; using this algorithm with an appropriate heuristic yields optimal behavior, hence A*.

		A game tree is a tree in which each node represents the state of the game, and a node's children are the states that can be reached from the node.
		On a search to depth 2, the number of states searched is COLS^2, 36.
		On a search to depth 3, the number of states search is COLS^3, 216.

	DiSC - Parallel R-Tree Search Algorithm on DSVM (Site not responding. Last check: 2007-09-17)
		Though parallel database systems have been extensively studied, as far as we know, the parallel algorithms of R-tree propsed so far are limited to one workstation with multiprocessors or multi disks, where parallel sorting algorithm or concurrent I/O is used to improve the performance.
		For the search of R-tree, multiple search paths from the root to leaves are traversed sequentially.
		In the paper, aiming at parallel I/O and CPU operations, we introduce a parallel R-tree search algorithm running on Distributed Shared Virtual Memory (DSVM), especially on Shusseuo which is an ODBMS providing global persistent object management on persistent DSVM.
