  2. 11. Integration of Constraint Programming and Integer Programming for Combinatorial Optimization

    Author : Greger Ottosson; Mats Carlsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi; Datalogi; Computing Science;

    Abstract : The last several years have seen an increasing interest in combining the models and methods of optimization with those of constraint programming. Integration of the two was initially impeded by their different cultural origins, one having developed largely in the operations research community and the other in the computer science and artificial intelligence communities.

  5. 13. A Study of Combinatorial Optimization Problems in Industrial Computer Systems

    Author : Markus Bohlin; Björn Lisper; Per Kreuger; Mikael Sjödin; Petru Eles; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi; Computer Science; datavetenskap;

    Abstract : A combinatorial optimization problem is an optimization problem where the number of possible solutions are finite and grow combinatorially with the problem size. Combinatorial problems exist everywhere in industrial systems. READ MORE

  6. 14. On Cooperative Surveillance, Online Trajectory Planning and Observer Based Control

    Author : David A. Anisi; Xiaoming Hu; Randal Beard; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surveillance Missions; Minimum-Time Surveillance; Unmanned Ground Vehicles; Connectivity Constraints; Combinatorial Optimization; Computational Optimal Control; Receding Horizon Control; Mission Uncertainty; Safety; Task Completion; Adaptive Grid Methods; Missile Guidance; Nonlinear Observer Design; Active Observers; Non--uniformly Observable Systems; Mobile Robotic Systems; Intrinsic Observers; Differential Geometric Methods; Euler-Lagrange Systems; Contraction Analysis.; Optimization; systems theory; Optimeringslära; systemteori; Applied mathematics; Tillämpad matematik;

    Abstract : The main body of this thesis consists of six appended papers. In the  first two, different  cooperative surveillance problems are considered. The second two consider different aspects of the trajectory planning problem, while the last two deal with observer design for mobile robotic and Euler-Lagrange systems respectively. READ MORE

  7. 15. Efficient Algorithms for Probabilistic Inference, Combinatorial Optimization and the Discovery of Causal Structure from Data

    Author : Dag Wedelin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In the first article we present a network based algorithm for probabilistic inference in an undirected structure. We show that the algorithm can be used as a general purpose approximation algorithm for combinatorial optimization, and discuss issues of approximation and convergence. READ MORE
