Near-medians that avoid the corners; a combinatorial probability approach. [PDF]

open access: goldBMC Genomics, 2014
The breakpoint median for a set of k ≥ 3 random genomes tends to approach (any) one of these genomes ("corners") as genome length increases, although there are diminishing proportion of medians equidistant from all k ("medians in the middle"). Algorithms are likely to miss the latter, and this has consequences for the general case where input genomes ...

Probability-boosting technique for combinatorial optimization [PDF]

open access: goldPeerJ Computer Science
In many combinatorial optimization problems we want a particular set of k out of n items with some certain properties (or constraints). These properties may involve the k items.

Possibilities determine the combinatorial structure of probability polytopes [PDF]

open access: greenJournal of Mathematical Psychology, 2016
We study the set of no-signalling empirical models on a measurement scenario, and show that the combinatorial structure of the no-signalling polytope is completely determined by the possibilistic information given by the support of the models. This is a special case of a general result which applies to all polytopes presented in a standard form, given ...

Generating Functions for New Families of Combinatorial Numbers and Polynomials: Approach to Poisson–Charlier Polynomials and Probability Distribution Function [PDF]

open access: goldAxioms, 2019
The aim of this paper is to construct generating functions for new families of combinatorial numbers and polynomials. By using these generating functions with their functional and differential equations, we not only investigate properties of these new ...

A combinatorial lemma and its application to probability theory [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1956
To explain the idea behind the present paper the following fundamental principle is emphasized. Let X = (X 1,…, X n ) be an n-dimensional vector valued random variable, and let µ(x) =µ(x 1…, x n )be its probability measure (defined on euclidean n-space E n ).

Probability and Problems in Euclidean Combinatorial Optimization [PDF]

open access: bronzeStatistical Science, 1993
This article summarizes the current status of several streams of research that deal with the probability theory of problems of combina- torial optimization. There is a particular emphasis on functionals of finite point sets. The most famous example of such functionals is the length associated with the Euclidean traveling salesman problem (TSP), but ...

Extremal Probability Bounds in Combinatorial Optimization [PDF]

open access: greenSIAM Journal on Optimization, 2021
In this paper, we compute the tightest possible bounds on the probability that the optimal value of a combinatorial optimization problem in maximization form with a random objective exceeds a given number, assuming only knowledge of the marginal distributions of the objective coefficient vector.

Scientific Creativity: Discovery and Invention as Combinatorial

open access: yesFrontiers in Psychology, 2021
Although scientific creativity has often been described as combinatorial, the description is usually insufficiently formulated to count as a precise scientific explanation.

Pheniqs 2.0: accurate, high-performance Bayesian decoding and confidence estimation for combinatorial barcode indexing

open access: yesBMC Bioinformatics, 2021

Combinatorial probability and the tightness of generalization bounds [PDF]

open access: yesPattern Recognition and Image Analysis, 2008
Accurate prediction of the generalization ability of a learning algorithm is an important problem in computational learning theory. The classical Vapnik-Chervonenkis (VC) generalization bounds are too general and therefore overestimate the expected error. Recently obtained data-dependent bounds are still overestimated.
