	Tabu Search (Site not responding. Last check: 2007-11-02)
		A distinguishing feature of tabu search is its exploitation of adaptive forms of memory, which equips it to penetrate complexities that often confound alternative approaches.
		Tabu search is concerned with finding new and more effective ways of taking advantage of the mechanisms associated with both adaptive memory and responsive exploration.
		Tabu search is attracting attention from a growing number researchers and practitioners, perhaps because it has a rationale that is transparent and natural: its goal is to emulate intelligent uses of memory, particularly for exploiting structure.

	GAUL: Genetic Algorithm Utility Library
		Unlike simple hill-climbing search techniques, but like simulated annealling, the Tabu search often moves from a current solution to one which is worse, with the expectation that this move will eventually lead to an even better solution.
		Tabu conditions: A set of rules which are used to derive, from the Tabu list, regions of the search space from which any solutions are forbidden.
		The Tabu search is implemented in GAUL and demonstrated in examples/pingpong_tabu.c and examples/pingpong_tabu2.c.

	Tabu search - Wikipedia, the free encyclopedia
		Tabu search is a mathematical optimization method, belonging to the class of local search techniques.
		Tabu search uses a local or neighbourhood search procedure to iteratively move from a solution x to a solution x' in the neighbourhood of x, until some stopping criterion has been satisfied.
		To explore regions of the search space that would be left unexplored by the local search procedure and—by doing this—escape local optimality, tabu search modifies the neighbourhood structure of each solution as the search progresses.

	Tabu Search
		Tabu search has important links to evolutionary and "genetic" methods, often overlooked, through its intimate connection with scatter search and path relinking-- evolutionary procedures that have recently attracted attention for their ability to facilitate the solution of complex problems.
		The adaptive memory designs of tabu search have also provided useful alternatives and supplements to the types of memory embodied in neural networks, allowing enhancements of neural network processes in practical settings.
		Tabu Search is designed to be useful and accessible to researchers and practitioners in management science, industrial engineering, economics, and computer science.

	[No title]
		Tabu search is originated from the surrogate constraint methods and the cutting plane approaches.
		Tabu search keeps a list, which is called tabu list, of the moves it used to obtain the best solutions during each iteration and to restrict the local search algorithm in reusing those moves.
		Tabu search is shown efficient in solving many difficult optimization problems in many literatures.

	Reactive Tabu Search
		The basic tabu mechanism based on prohibitions is not sufficient to avoid long cycles In addition, even if ``limit cycles'' (endless cyclic repetitions of a given set of configurations) are avoided, the first reactive mechanism is not sufficient to guarantee that the search trajectory is not confined in a limited region of the search space.
		The Reactive Search framework and, in particular, the RTS algorithm have been and are being applied to a growing number of discrete optimization problems, continuos optimization tasks, and different problems arising in the context of sub-symbolic machine learning.
		In particular, in the Reactive Tabu Search (RTS) algorithm a simple feedback scheme influences the value of the prohibition parameter in Tabu Search, so that a balance of exploration versus exploitation is obtained that is appropriate for the local characteristics of the task.

	Tabu Search (Site not responding. Last check: 2007-11-02)
		A tabu search is basically a series of line minimizations with two extra caveats.
		A simple line search takes the descriptor located in the first position and replaces it with each of the 35 descriptors that are not in the first five positions of the solution array.
		If this position is not on the tabu list, it is scanned, its descriptor is replaced by the new one with the lowest MSE, and that position is add to the top of the tabu list with each other member of the list moving down one position.

	Tabu Search (via CobWeb/3.1 planetlab2.cs.umd.edu) (Site not responding. Last check: 2007-11-02)
		The basic concept of Tabu Search as described by Glover (1986) is "a meta-heuristic superimposed on another heuristic.
		The Tabu method was partly motivated by the observation that human behavior appears to operate with a random element that leads to inconsistent behavior given similar circumstances.
		Instead the Tabu search proceeds according to the supposition that there is no point in accepting a new (poor) solution unless it is to avoid a path already investigated.

		Tabu search is an iterative procedure for solving optimization problems.
		The basic idea of tabu search is to explore the search space of all feasible solutions by a sequence of moves.
		Tabu moves are derived from the short-term and long-term history of the sequence of moves.

	Tabu Search
		Local search employs the idea that a given solution S may be improved by making small changes.
		Those solutions obtained by modifying solution S are called neighbors of S. The local search algorithm starts with some initial solution and moves from neighbor to neighbor as long as possible while decreasing the objective function value.
		Tabu search allows the search to explore solutions that do not decrease the objective function value only in those cases where these solutions are not forbidden.

	AN INTRODUCTION TO TABU SEARCH
		The search space of an LS or TS heuristic is simply the space of all possible solutions that can be considered (visited) during the search.
		Tabus are stored in a short-term memory of the search (the tabu list) and usually only a fixed and fairly limited quantity of information is recorded.
		Tabu Search is a powerful algorithmic approach that has been applied with great success to many difficult combinatorial problems.

	An improved tabu search method for the weighted constraint satisfaction problem INFOR - Find Articles (Site not responding. Last check: 2007-11-02)
		We propose a tabu search algorithm for WCSP with the features that it uses an evaluation function, defined in terms of the modified weights of constraints, for guiding the search, and that it incorporates an automatic control mechanism of the weights in the evaluation function.
		Tabu search is a variant of the local search algorithms in which the search history is utilized to make the remaining search process more efficient [15, 16].
		In this paper, we describe how the previous tabu search algorithm is modified and improved.

	BA-Cluster
		In the Tabu Search method, in order to improve the efficiency of the exploration process, some historical information related to the evolution of the search is kept (basically the itinerary through the solutions visited).
		Typically there are two kinds of tabu lists, a long term memory maintaining the history through all the exploration process as a whole and a short term memory to keep the most recently visited tabu movements.
		Given that the tabu list size is fixed before the hand each element of the list belongs to it for a number of iterations bounded by given maximum and minimum values.

		Local search employs the idea that a given solution S may be improved by a series of small changes.
		Those solutions obtained by modifying solution S are called neighbors of S. The local search algorithm starts with some initial solution and moves from neighbor to neighbor as long as it is possible to decrease the objective function value.
		The main problem with this strategy is how to escape from local minima that is, those points in which the search cannot find any further neighborhood solution that decreases the objective function value.

	SolveIT Software - Tabu Search
		Tabu Search is an iterative procedure for solving discrete combinatorial optimization problems.
		However, to escape from locally optimal but not globally optimal solutions, and to prevent cycling, some moves (at one particular iteration) are classified as forbidden or “tabu.” Tabu moves are based on the short-term and long-term history of the sequence of moves.
		A simple implementation, for example, might classify a move as tabu if the reverse move has been made recently or frequently.

	Local Search and Tabu Search
		Clearly, local search stops as soon as the first local optimum point is encountered, when no improving moves are available, see eqn.
		Tabu Search (TS) is a history-sensitive heuristic proposed by F. Glover [11] and, independently, by Hansen and Jaumard, that used the term SAMD (``steepest ascent mildest descent'') and applied it to the MAX-SAT problem in [19].
		The main mechanism by which the history influences the search in TS is that, at a given iteration, some neighbors are prohibited, only a non-empty subset
