Frontier search

Richard E. Korf, Weixiong Zhang, Ignacio Thayer, Heath Hohwald
2005 Journal of the ACM  
For many problems, frontier search dramatically reduces the memory required by best-first search.  ...  We apply frontier search to breadth-first search of sliding-tile puzzles and the 4-peg Towers of Hanoi problem, Dijkstra's algorithm on a grid with random edge costs, and the A* algorithm on the Fifteen  ...  Thanks to Hermann Kaindl for information on bidirectional search.  ...

A Multiobjective Frontier Search Algorithm

Lawrence Mandow, José-Luis Pérez-de-la-Cruz
2007 International Joint Conference on Artificial Intelligence  
The paper analyzes the extension of frontier search to the multiobjective framework.  ...  A frontier multiobjective A* search algorithm is developed, some formal properties are presented, and its performance is compared to those of other multiobjective search algorithms.  ...  Section 2 describes scalar frontier search. Section 3 examines the fundamental issues in multiobjective search and introduces a frontier multiobjective A* search algorithm.  ...

Spider Search: An Efficient and Non-Frontier-Based Real-Time Search Algorithm

Chao Lin Chu, Russell J. Abbott, Debora K. Shuger
2008 2008 Eighth International Conference on Intelligent Systems Design and Applications  
The standard searches discussed below and LRTA* are both frontier-based searches.  ...  We expect that Spider search is the first in a new class of tree-based rather than frontier-based search algorithms.  ...

Frontier Search and Plan Reconstruction in Oversubscription Planning

Daniel Muller
We now propose a progressive frontier search algorithm, which alleviates the need to re-start from scratch once new information is acquired by capturing the frontier achieved at the end of each iteration  ...  Each iteration requires search re-start in order to exploit the new knowledge obtained along the search.  ...  Our technique allows the new search iteration to continue from any state on the frontier of the previous search iteration, leading to improved efficiency of the search.  ...

b→stransitions: A new frontier for indirect supersymmetry searches

M. Ciuchini, E. Franco, A. Masiero, L. Silvestrini
2003 Physical Review D, Particles and fields  
constrain different MSSM realizations, and, even more important, that they offer concrete prospects to exhibit SUSY signals at B factories and hadron colliders in spite of all the past frustration in FCNC searches  ...  We hope that we made the case for b → s physics in the search for indirect SUSY signals quite clear.  ...  And at that point, one would be tempted to say, we will know whether low energy SUSY is there just by direct tests without invoking the indirect searches that we advocated in this work.  ...

Search for Hidden Particles in Intensity Frontier Experiment SHiP

V. M. Gorkavenko
2019 Ukrainian Journal of Physics  
There are many experiments to search for new physics that can be can divided into two types: energy and intensity frontiers.  ...  The future intensity frontier SHiP experiment (Search for Hidden Particles) at the CERN SPS is discussed. Its advantages and technical characteristics are given.  ...  So, in the intensity frontier experiments, we search for very rare events.  ...

A 2-Dimensional Binary Search for Integer Pareto Frontiers [article]

Yotam Gafni
2022 arXiv   pre-print
We show that a generalization of the binary search algorithm achieves an optimal θ(n) worst-case run time.  ...  There is a classification function I : G → {0, 1} that respects Pareto domination [3] : Pareto frontier Given a set S with tuple elements of the form (x, y), we say F (S) is the Pareto frontier of S if  ...  Since I respects Pareto domination, it is uniquely defined by a Pareto frontier of some set S ⊆ G. Lemma 1. There is a 1-1 mapping between classification functions I and Pareto frontiers in G.  ...

Top quark theory and the new physics searches frontier

Gilad Perez
2013 Physica Scripta  
The notion of 'mini' intensity and energy frontiers at the LHC is then explained with an example given for each of these fronts.  ...  We briefly report on the current status of the Large Hadron Collider (LHC) 'battle of naturalness' related to top partner searches.  ...  However, what is really singling out top physics as a major player in the new physics searches frontier is the fine tuning problem.  ...
