Microscopy as a statistical, Rényi-Ulam, half-lie game: a new heuristic search strategy to accelerate imaging

Daniel W. Drumm, Andrew D. Greentree
2017 Scientific Reports  
We show the cost of insisting on verification by positive result in search algorithms; for the zero-half-lie case bisectioning with verification incurs a 50% penalty in the average number of queries required  ...  The case of half-lies, where one of two responses to a search query may be deceptive, introduces a richer, R\'enyi-Ulam problem and is particularly relevant to practical microscopy.  ...  numbers CE140100003 and FT160100357).  ...

Filtering Search: A New Approach to Query-Answering

Bernard Chazelle
1986 SIAM journal on computing (Print)  
The approach which we take is very general and rests on a new concept called filtering search.  ...  We introduce a new technique for solving problems of the following form: preprocess a set of objects so that those satisfying a given property with respect to a query object can be listed very effectively  ...  I wish to thank Jon Bentley, Herbert Edelsbrunner, Janet Incerpi, and the anonymous referees for many valuable comments.  ...

An Optimal Dynamic Data Structure for Stabbing-Semigroup Queries

Pankaj K. Agarwal, Lars Arge, Haim Kaplan, Eyal Molad, Robert E. Tarjan, Ke Yi
2012 SIAM journal on computing (Print)  
For a point x ∈ R, let S(x) ⊆ S be the set of intervals that contain x. Given a point q ∈ R, the stabbing-semigroup query asks for computing s∈S(q) ω(s).  ...  Alternatively, by using an interval tree [9] one can obtain a linear-size data structure that supports both insertions and deletions in O(log n) time but requires O(log 2 n) time to answer a query.  ...  The authors thank Mihai Pǎtraşcu for helpful discussions on the lower bound of the problem. They also thank two anonymous referees for their useful comments.  ...

Largest components in random hypergraphs [article]

Oliver Cooley, Mihyun Kang, Yury Person
2014 arXiv   pre-print
Our proof extends the recent short proof for the graph case by Krivelevich and Sudakov which makes use of a depth-first search to reveal the edges of a random graph.  ...  In this paper we consider j-tuple-connected components in random k-uniform hypergraphs (the j-tuple-connectedness relation can be defined by letting two j-sets be connected if they lie in a common edge  ...  Thus τ P defines a probability distribution on N. Lemma 16. For any m, r, s ∈ N and 1/r ≥ q ∈ R, Pr(τ r·Bi(m,q) ≤ rs) ≥ Pr(τ Bi(rm,q) ≤ s). Proof.  ...

The size of the giant component in random hypergraphs [article]

Oliver Cooley, Mihyun Kang, Christoph Koch
2015 arXiv   pre-print
In this paper we build on this and determine the asymptotic size of the unique giant component.  ...  The phase transition in the size of the giant component in random graphs is one of the most well-studied phenomena in random graph theory.  ...  We first borrow a lemma from [5] , which states that we may pick out a subsequence of queries and treat it like an interval of the search process.  ...

Blind Seer: A Scalable Private DBMS

Vasilis Pappas, Fernando Krell, Binh Vo, Vladimir Kolesnikov, Tal Malkin, Seung Geol Choi, Wesley George, Angelos Keromytis, Steve Bellovin
2014 2014 IEEE Symposium on Security and Privacy  
We support a rich query set, including searching on arbitrary boolean formulas on keywords and ranges, support for stemming, and free keyword searches over text fields.  ...  We also support private and complex access policies, integrated in the search process so that a query with empty result set and a query that fails the policy are hard to tell apart. Design goals.  ...  Any opinion, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.  ...

Christos Levcopoulos, Andrzej Lingas, Jörg-R. Sack
1989 Theoretical Computer Science  
In this paper we establish new bounds on the problem of constructing optimum binary search trees with zero-key access probabilities (with applications e.g. to point location problems).  ...  They are carried over to binary search trees by proving a duality between optimum (m -I)-way search trees and minimum weight partitions of infinitely-flat semi-circular polygons into m-gons.  ...  among all m-ary search trees for S.  ...
