A hybrid GRASP heuristic to construct effective drawings of proportional symbol maps

Rafael G. Cano, Guilherme Kunigami, Cid C. de Souza, Pedro J. de Rezende
2013 Computers & Operations Research  
Proportional symbol map is a cartographic tool that employs symbols to represent data associated with specific locations.  ...  Each symbol is drawn at the location of an event and its size is proportional to the numerical data collected at that point on the map. The symbols considered here are opaque disks.  ...  Conclusion In this paper, we proposed a hybrid GRASP heuristic with VNS and path-relinking for the Max-Total problem for stacking drawings of symbol maps.  ...

Fuzzy optimisation based symbolic grounding for service robots

B. Liu, D. Li, R. Qiu, Y. Yue, C. Maple, S. Gu
2012 2012 IEEE/RSJ International Conference on Intelligent Robots and Systems  
This approach can handle uncertainties and helps service robots to determine the most comfortable base region for grasping objects in a fetch and carry task.  ...  In this research, a fuzzy optimisation based symbolic grounding approach is presented.  ...  The optimisation is conducted through a hybrid heuristic method that combines the advantages of a genetic algorithm (GA), a quasi-Newton algorithm (QNA) and a constraints handling method (CHM).  ...

Strategies for the Parallel Implementation of Metaheuristics [chapter]

Van-Dat Cung, Simone L. Martins, Celso C. Ribeiro, Catherine Roucairol
2002 Operations Research/Computer Science Interfaces Series  
Parallel implementations of metaheuristics appear quite naturally as an effective alternative to speed up the search for approximate solutions of combinatorial optimization problems.  ...  Parallel implementations of tabu search, GRASP, genetic algorithms, simulated annealing, and ant colonies are reviewed and discussed to illustrate the main strategies used in the parallelization of different  ...  [134] implemented a parallel GRASP for the Steiner problem in graphs. The construction phase is based on a probabilistic version of the distance network heuristic [138] .  ...

A topolographical approach to infrastructure: Political topography, topology and the port of Dar es Salaam

Jana Hönke, Ivan Cuesta-Fernandez
2017 Environment & Planning. D, Society and Space  
This article proposes a 'topolographical' approach -a combined heuristic drawing from political topography and topology -to comprehend more fully the transformations in the political geographies of large-scale  ...  The cardinal nature of the port of Dar es Salaam makes it a crucial site through which to illustrate the purchase of this framework.  ...  We are also grateful to the editors and three anonymous reviewers of Society & Space for their thoughtful comments. Special thanks go to the fantastic participants of the New Political Topographies.  ...

Tabu Search and Adaptive Memory Programming — Advances, Applications and Challenges [chapter]

Fred Glover
1997 Operations Research/Computer Science Interfaces Series  
Specific tabu search applications are also summarized to provide a clearer understanding of settings where the method is being used.  ...  We examine basic concepts and principles of tabu search, emphasizing those that have sometimes led to applying the label "adaptive memory programming" to this class of methods.  ...  step is activated, which consists of making a number of random moves proportional to a moving average of the cycle length.  ...

Learning compositional models of robot skills for task and motion planning [article]

Zi Wang, Caelan Reed Garrett, Leslie Pack Kaelbling, Tomás Lozano-Pérez
2021 arXiv   pre-print
The objective of this work is to augment the basic abilities of a robot by learning to use sensorimotor primitives to solve complex long-horizon manipulation problems.  ...  We use Gaussian process methods for learning the constraints on skill effectiveness from small numbers of expensive-to-collect training examples.  ...  Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of our sponsors.  ...

How to improve Bayesian reasoning without instruction: Frequency formats

Gerd Gigerenzer, Ulrich Hoffrage
1995 Psychological review  
However, any claim against the existence of an algorithm, Bayesian or otherwise, is impossible to evaluate unless one specifies the information format in which it is designed to operate.  ...  By analyzing several thousand solutions to Bayesian problems, the authors found that when information was presented in frequency formats, statistically naive participants derived up to 50% of all inferences  ...  These representations can be mapped one to one onto each other and are in this sense mathematically equivalent.  ...
