2003 Discrete Applied Mathematics  
Various results concerning the domination search number of a graph are presented.  ...  We introduce the domination search game which can be seen as a natural modification of the well-known node search game.  ...  1 Notice that the domination search number of a disconnected graph G is equal to the maximum domination search number taken over all components of G.  ...

A note on the independence number, domination number and related parameters of random binary search trees and random recursive trees [article]

Michael Fuchs, Cecilia Holmgren, Dieter Mitsche, Ralph Neininger
2020 arXiv   pre-print
We identify the mean growth of the independence number of random binary search trees and random recursive trees and show normal fluctuations around their means.  ...  Similarly we also show normal limit laws for the domination number and variations of it for these two cases of random tree models.  ...  The authors thank the participants, in particular Luc Devroye and Remco van der Hofstad, for helpful discussions on the present problem.  ...

Generalization of Dominance Relation-Based Replacement Rules for Memetic EMO Algorithms [chapter]

Tadahiko Murata, Shiori Kaige, Hisao Ishibuchi
2003 Lecture Notes in Computer Science  
Ordinary two replacement rules based on the dominance relation are usually employed in a local search (LS) for multiobjective optimization.  ...  In this paper, we generalize the replacement rules based on the dominance relation in multiobjective optimization.  ...  We generalize the replacement rules based on the dominance relation by counting the number of better objective values.  ...

'Dominating-set-based' searching in peer-to-peer networks

Chunlin Yang, Xiuqi Li
2005 International Journal of High Performance Computing and Networking  
This approach is based on random walk. However, the searching space is restricted to dominating nodes. Simulation has been done and results are compared with the one using regular random walk.  ...  In this paper, we propose a dominating-set-based peer-to-peer searching algorithm to maximize the return of searching results while keeping a low cost for both searching and creating/maintaining the connecteddominating-set  ...  We used 20 hops as the maximum number for both searching methods. In Table II number of hops using) dominating-set-based searching.  ...

Web-page Indexing based on the Prioritize Ontology Terms [article]

Sukanta Sinha, Rana Dattagupta, Debajyoti Mukhopadhyay
2013 arXiv   pre-print
The proposed Webpage indexing mechanism has applied on domain specific Webpages and we have identified the Webpage domain based on an Ontology.  ...  The Webpage indexing mechanism of a search engine plays a big role to retrieve Web search results in a faster way from the huge volume of Web resources.  ...  After providing all the inputs, i.e., search tokens, relevance range and number of search results, Web searcher need to click on "Search" button to get the search results.  ...

Improved Solution to the Non-Domination Level Update Problem [article]

Sumit Mishra, Samrat Mondal, Sriparna Saha
2015 arXiv   pre-print
In case of insertion, the tree based approach always checks for same number of fronts unlike linear approach in which the number of fronts to be checked depends on the inserted solution.  ...  Generally the solution to this problem requires to perform the complete non-dominated sorting which is too expensive in terms of number of comparisons.  ...  In place of Algorithm 5 which is based on Left Dominance Binary Search Tree, Algorithm 6 can also be used which is based on Right Dominance Binary Search Tree.  ...

Link enhancement using constrained range and reduced candidate set searches: a revision

Ruey-yih Lin, Chyan Yang
1995 Computer Communications  
Two major improvements are proposed: first, by combining information on the cost and performance of candidate links, we obtain the exact number of links in one step without compromising optimality and  ...  Moreover, we use the concept of variable dominance to reduce the number of candidate links without loss of optimality.  ...  When we use the reduced candidate set to find the optimal solution, we can use information on the dominated sets to generate new constraints in order to make the search procedure more efficient, i.e. if  ...

Minimal dominating sets in graph classes: Combinatorial bounds and enumeration

Jean-François Couturier, Pinar Heggernes, Pim van 't Hof, Dieter Kratsch
2013 Theoretical Computer Science  
And bound the number of leaves in the search tree is exactly what an estimation of execution time does. What is the maximum number of minimal dominating sets in a graph on n vertices ?  ...  If we can bound the number of leaves in the search tree, we bound at the same time the number of solutions of the problem !  ...

The Effect of Social Hierarchy on Captive Coyote (Canis latrans) Foraging Behavior

Lynne B. Gilbert-Norton, Ryan R. Wilson, John A. Shivik, D. Zeh
2013 Ethology  
That is, subordinates approached the correct area, but searched more feeders before finding the correct one.  ...  To examine the impact of social hierarchy on foraging behavior, we tested 16 captive coyotes in eight naturally established dominant-subordinate pairs, using the guesser-knower paradigm.  ...  We gratefully acknowledge the financial and technical support provided by the USDA, Wildlife Service's National Wildlife Research Center.  ...

An Efficient Approach to Nondominated Sorting for Evolutionary Multiobjective Optimization

Xingyi Zhang, Ye Tian, Ran Cheng, Yaochu Jin
2015 IEEE Transactions on Evolutionary Computation  
Based on this new approach, two non-dominated sorting algorithms have been suggested.  ...  This technique, however, can be computationally expensive, especially when the number of individuals in the population becomes large.  ...  Two non-dominated sorting algorithms based on the ENS approach have been implemented, one using the sequential search strategy and the other using the binary search strategy to locate the front to which  ...

A tree-search algorithm for ML decoding in underdetermined MIMO systems

G. Romano, F. Palmieri, P. Salvo Rossi, D. Mattera
2009 2009 6th International Symposium on Wireless Communication Systems  
Also a two-stage tree-search algorithm is presented based on the idea that the ML solution is in the set of equilibrium points of a Hopfield Neural Networks (HNN).  ...  In this paper we propose a tree-search algorithm that provides the exact ML solution with lower computational complexity than that required by an exhaustive search of minimum distance.  ...  The algorithms are based on the dominance condition and on the HNN equilibrium condition, that provide simple conditions for a reduction of the number of points for which compute the euclidean distance  ...

Heuristics for k-domination models of facility location problems in street networks

Padraig Corcoran, Andrei Gagarin
2021 Computers & Operations Research  
For the classic minimum dominating set (1-domination) problem, all except one methods perform similarly, which is due to their equivalence in this particular case.  ...  We present new greedy and beam search heuristic methods to find small-size k-dominating sets in graphs.  ...  The authors evaluated this method against a randomized local search method and the standard greedy search heuristic [15] on a number of real-world graphs.  ...
