A RANDOMIZED ALGORITHM FOR SLOPE SELECTION

International Journal of Computational Geometry & Applications, 1992
A set of n distinct points in the plane defines [Formula: see text] lines by joining each pair of distinct points. The median slope of these O(n2) lines was proposed by Theil as a robust estimator for the slope of the line of best fit for the points. We present a randomized algorithm for selecting the k-th smallest slope of such a set of lines which ...

Randomized algorithms on the mesh

1998
The mesh-connected array is an attractive architecture for parallel machines, and a number of existing parallel machines are based on a mesh topology. In this paper, we survey the results on three fundamental problems in parallel computation: routing, sorting, and selection, and demonstrate that randomized algorithms for these problems on the mesh are ...

Randomized algorithms and pseudorandom numbers

Proceedings of the twentieth annual ACM symposium on Theory of computing - STOC '88, 1988
Summary: Randomized algorithms are analyzed as if unlimited amounts of perfect randomness were available, while pseudorandom number generation is usually studied from the perspective of cryptographic security or for the statistical properties of the numbers generated. \textit{E. Bach} [J. Comput. Syst. Sci. 42, No.

Randomized Algorithms for Lexicographic Inference

Operations Research, 2019
Summary: The inference of a lexicographic rule from paired comparisons, ranking, or choice data is a discrete optimization problem that generalizes the linear ordering problem. We develop an approach to its solution using randomized algorithms. First, we show that maximizing the expected value of a randomized solution is equivalent to solving the ...

The Reliability of Randomized Algorithms

The British Journal for the Philosophy of Science, 2000
Recently, certain philosophers of mathematics (Fallis [1997]; Womack and Farach [1997]) have argued that there are no epistemic considerations that should stop mathematicians from using probabilistic methods to establish that mathematical propositions are true. However, mathematicians clearly should not use methods that are unreliable.

Randomized algorithms in robust control

42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004
The probabilistic approach to analysis and design of robust control systems is an emerging philosophy that gained increasing interest in the past. Opposed to the so-far dominating paradigm of deterministic worst-case robustness, the probabilistic approach presents itself as a natural tool to deal with the random character of uncertainties affecting ...

On Assessing the Performance of Randomized Algorithms

Journal of Algorithms, 2000
Summary: We study randomized algorithms with random input. We adapt to such algorithms the notion of probability of a false positive which is common in epidemiological studies. The probability of a false positive takes into account both the (controlled) error of the randomization and the randomness of the input, which needs to be modeled. We illustrate

Introduction to randomized algorithms

1998
This chapter presents a short introduction to randomized algorithms, demonstrating their usefulness by showing that an essentially trivial randomized algorithm for MAXE3SAT (the version of MAX3SAT in which all clauses have exactly three literals) has expected performance ratio 8/7.
