Download or read book Heuristic Search written by Stefan Edelkamp and published by Elsevier. This book was released on 2011-05-31 with total page 865 pages. Available in PDF, EPUB and Kindle. Book excerpt: Search has been vital to artificial intelligence from the very beginning as a core technique in problem solving. The authors present a thorough overview of heuristic search with a balance of discussion between theoretical analysis and efficient implementation and application to real-world problems. Current developments in search such as pattern databases and search with efficient use of external memory and parallel processing units on main boards and graphics cards are detailed. Heuristic search as a problem solving tool is demonstrated in applications for puzzle solving, game playing, constraint satisfaction and machine learning. While no previous familiarity with heuristic search is necessary the reader should have a basic knowledge of algorithms, data structures, and calculus. Real-world case studies and chapter ending exercises help to create a full and realized picture of how search fits into the world of artificial intelligence and the one around us. Provides real-world success stories and case studies for heuristic search algorithms Includes many AI developments not yet covered in textbooks such as pattern databases, symbolic search, and parallel processing units

Available in PDF, EPUB and Kindle. Book excerpt: Bidirectional heuristic search is a well-known technique for solving pathfinding problems. The goal in a pathfinding problem is to find paths---often of lowest cost---between nodes in a graph. Many real-world problems, such as finding the quickest route between two points in a map or measuring the similarity of DNA sequences, can be modeled as pathfinding problems. Bidirectional brute-force search does simultaneous brute-force searches forward from the initial state and backward from the goal states, finding solutions when both intersect. The idea of adding a heuristic to guide search is an old one, but has not seen widespread use and is generally believed to be ineffective. I present an intuitive explanation for the ineffectiveness of front-to-end bidirectional heuristic search. Previous work has examined this topic, but mine is the first comprehensive explanation for why most front-to-end bidirectional heuristic search algorithms will usually be outperformed by either unidirectional heuristic or bidirectional brute-force searches. However, I also provide a graph wherein bidirectional heuristic search does outperform both other approaches, as well as real-world problem instances from the road navigation domain. These demonstrate that there can be no general, formal proof of the technique's ineffectiveness. I tested my theory in a large number of popular search domains, confirming its predictions. One of my experiments demonstrates that a commonly-repeated explanation for the ineffectiveness of bidirectional heuristic search---that it spends most of its time proving solution optimality---is in fact wrong, and that with a strong heuristic a bidirectional heuristic search tends to find optimal solutions very late in a search. Finally, I introduce state-of-the-art solvers for the four-peg Towers of Hanoi with arbitrary initial and goal states, and peg solitaire, using disk-based, bidirectional algorithms. The Towers of Hanoi solver is a bidirectional brute-force solver which, as my theory predicts, outperforms a unidirectional heuristic solver. The peg solitaire solver is a bidirectional heuristic algorithm with novel heuristics. While my theory demonstrates that bidirectional heuristic search is generally ineffective, the peg solitaire domain demonstrates several caveats to my theory that this algorithm takes advantage of.

Download or read book The Shortest-Path Problem written by Hector Ortega-Arranz and published by Springer Nature. This book was released on 2022-05-31 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many applications in different domains need to calculate the shortest-path between two points in a graph. In this paper we describe this shortest path problem in detail, starting with the classic Dijkstra's algorithm and moving to more advanced solutions that are currently applied to road network routing, including the use of heuristics and precomputation techniques. Since several of these improvements involve subtle changes to the search space, it may be difficult to appreciate their benefits in terms of time or space requirements. To make methods more comprehensive and to facilitate their comparison, this book presents a single case study that serves as a common benchmark. The paper also compares the search spaces explored by the methods described, both from a quantitative and qualitative point of view, and including an analysis of the number of reached and settled nodes by different methods for a particular topology.

Available in PDF, EPUB and Kindle. Book excerpt: Search is an important component of problem solving in artificial intelligence (AI) and, more generally, in computer science, engineering and operations research. Combinatorial optimization, decision analysis, game playing, learning, planning, pattern recognition, robotics and theorem proving are some of the areas in which search algbrithms playa key role. Less than a decade ago the conventional wisdom in artificial intelligence was that the best search algorithms had already been invented and the likelihood of finding new results in this area was very small. Since then many new insights and results have been obtained. For example, new algorithms for state space, AND/OR graph, and game tree search were discovered. Articles on new theoretical developments and experimental results on backtracking, heuristic search and constraint propaga tion were published. The relationships among various search and combinatorial algorithms in AI, Operations Research, and other fields were clarified. This volume brings together some of this recent work in a manner designed to be accessible to students and professionals interested in these new insights and developments.

Available in PDF, EPUB and Kindle. Book excerpt: The ?eld of robotics continues to ?ourish and develop. In common with general scienti?c investigation, new ideas and implementations emerge quite spontaneously and these are discussed, used, discarded or subsumed at c- ferences, in the reference journals, as well as through the Internet. After a little more maturity has been acquired by the new concepts, then archival publication as a scienti?c or engineering monograph may occur. The goal of the Springer Tracts in Advanced Robotics is to publish new developments and advances in the ?elds of robotics research – rapidly and informally but with a high quality. It is hoped that prospective authors will welcome the opportunity to publish a structured presentation of some of the emerging robotics methodologies and technologies. The edited volume by Antonio Bicchi, Henrik Christensen and Domenico Prattichizzo is the outcome of the second edition of a workshop jointly sponsored by the IEEE Control Systems Society and the IEEE Robotics and Automation Society. Noticeably, the previous volume was published in the Springer Lecture Notes on Control and Information Sciences. The authors are recognised as leading scholars internationally. A n- ber of challenging control problems on the forefront of today’s research in robotics and automation are covered, with special emphasis on vision, sensory-feedback control, human-centered robotics, manipulation, planning, ?exible and cooperative robots, assembly systems.

Book excerpt: The Computers and Games (CG) series began in 1998 with the objective of showcasing new developments in arti?cial intelligence (AI) research that used games as the experimental test-bed. The ?rst two CG conferences were held at Hamamatsu,Japan(1998,2000).ComputersandGames2002(CG2002)wasthe third event in this biennial series. The conference was held at the University of Alberta(Edmonton,Alberta,Canada),July25–27,2002.Theprogramconsisted of the main conference featuring refereed papers and keynote speakers, as well as several side events including the Games Informatics Workshop, the Agents in Computer Games Workshop, the Trading Agents Competition, and the North American Computer Go Championship. CG 2002 attracted 110 participants from over a dozen countries. Part of the successoftheconferencewasthatitwasco-locatedwiththeNationalConference of the American Association for Arti?cial Intelligence (AAAI), which began in Edmonton just as CG 2002 ended. The CG 2002 program had 27 refereed paper presentations. The papers ranged over a wide variety of AI-related topics including search, knowledge, learning, planning, and combinatorial game theory. Research test-beds included one-player games (blackjack, sliding-tile puzzles, Sokoban), two-player games (Amazons, awari, chess, Chinese chess, clobber, Go, Hex, Lines of Action, O- ello, shogi), multi-player games (Chinese checkers, cribbage, Diplomacy, hearts, spades), commercial games (role-playing games, real-time strategy games), and novel applications (Post’s Correspondence Problem).

Available in PDF, EPUB and Kindle. Book excerpt: "... In this thesis, we discuss solving this problem with generic heuristic search algorithms. Since LSP is a maximization problem and the generic algorithms designed for minimization problem we will modify them as offered by Stern et al [21]. We will present a variety of novel methods that aid in this problem such as new heuristics, pruning and preprocessing phase. We have used the prominent heuristic search algorithms A*, and Depth First Branch and Bound (DFBnB) with adaptions to maximization. Then, we have carried out hundreds of experiments with tens of combinations per heuristics, pruning and preprocessing. Our experiment analysis shows that the suggested methods improve the ability to solve the LSP problem tremendously both in the aspect of expanded states (factor of 20) and runtime (factor of 100). We also discuss the tradeoff of strong heuristic that is hard to compute and therefore results in bad runtime. We think that improving this heuristic can be the next state-of-art solution to LSP."-- from the abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Computational intelligence is a well-established paradigm, where new theories with a sound biological understanding have been evolving. The current experimental systems have many of the characteristics of biological computers (brains in other words) and are beginning to be built to perform a variety of tasks that are difficult or impossible to do with conventional computers. As evident, the ultimate achievement in this field would be to mimic or exceed human cognitive capabilities including reasoning, recognition, creativity, emotions, understanding, learning and so on. This book comprising of 17 chapters offers a step-by-step introduction (in a chronological order) to the various modern computational intelligence tools used in practical problem solving. Staring with different search techniques including informed and uninformed search, heuristic search, minmax, alpha-beta pruning methods, evolutionary algorithms and swarm intelligent techniques; the authors illustrate the design of knowledge-based systems and advanced expert systems, which incorporate uncertainty and fuzziness. Machine learning algorithms including decision trees and artificial neural networks are presented and finally the fundamentals of hybrid intelligent systems are also depicted. Academics, scientists as well as engineers engaged in research, development and application of computational intelligence techniques, machine learning and data mining would find the comprehensive coverage of this book invaluable.

Book excerpt: Algorithm Engineering is a methodology for algorithmic research that combines theory with implementation and experimentation in order to obtain better algorithms with high practical impact. Traditionally, the study of algorithms was dominated by mathematical (worst-case) analysis. In Algorithm Engineering, algorithms are also implemented and experiments conducted in a systematic way, sometimes resembling the experimentation processes known from fields such as biology, chemistry, or physics. This helps in counteracting an otherwise growing gap between theory and practice.
