Short Paper - A Note on Robust Combinatorial Optimization with Generalized Interval Uncertainty

open access: yesOpen Journal of Mathematical Optimization, 2023
In this paper, we consider a robust combinatorial optimization problem with uncertain weights and propose an uncertainty set that generalizes interval uncertainty by imposing lower and upper bounds on deviations of subsets of items.

Encoded expansion: an efficient algorithm to discover identical string motifs.

open access: yesPLoS ONE, 2014
A major task in computational biology is the discovery of short recurring string patterns known as motifs. Most of the schemes to discover motifs are either stochastic or combinatorial in nature. Stochastic approaches do not guarantee finding the correct

Universally Balanced Combinatorial Optimization Games

open access: yesGames, 2010
This article surveys studies on universally balanced properties of cooperative games defined in a succinct form. In particular, we focus on combinatorial optimization games in which the values to coalitions are defined through linear optimization ...

Combinatorial Stratification of Complex Arrangements [PDF]

open access: yesJournal of the American Mathematical Society, 1992
We present a method for discretizing complex hyperplane arrangements by encoding their topology into a finite partially ordered set of “sign vectors.” This is used in the following ways: (1) A general method is given for constructing regular cell complexes having the homotopy type of the complement of the arrangement.

Sequence conservation and combinatorial complexity of Drosophila neural precursor cell enhancers

open access: yesBMC Genomics, 2008
Background The presence of highly conserved sequences within cis-regulatory regions can serve as a valuable starting point for elucidating the basis of enhancer function.

Maximum Likelihood Joint Tracking and Association in Strong Clutter

open access: yesInternational Journal of Advanced Robotic Systems, 2013
We have developed a maximum likelihood formulation for a joint detection, tracking and association problem. An efficient non-combinatorial algorithm for this problem is developed in case of strong clutter for radar data.

Combinatorial Abstractions of Dynamical Systems [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
Formal verification has been successfully developed in computer science for verifying combinatorial classes of models and specifications. In like manner, formal verification methods have been developed for dynamical systems.
