Fast averaging [PDF]

open access: yes2011 IEEE International Symposium on Information Theory Proceedings, 2011
We are interested in the following question: given n numbers x[subscript 1], ..., x[subscript n], what sorts of approximation of average x[subscript ave] = 1overn (x[subscript 1] + ... + x[subscript n]) can be achieved by knowing only r of these n numbers. Indeed the answer depends on the variation in these n numbers.

Fast fencing

open access: yesProceedings of the 50th Annual ACM SIGACT Symposium on Theory of Computing, 2018
We consider very natural "fence enclosure" problems studied by Capoyleas, Rote, and Woeginger and Arkin, Khuller, and Mitchell in the early 90s. Given a set $S$ of $n$ points in the plane, we aim at finding a set of closed curves such that (1) each point is enclosed by a curve and (2) the total length of the curves is minimized.

Examination of Dyeing Properties of the Dyed Organic Cotton Knitting Fabrics Using Yarrow (Achillea Biebersteinii AFAN and Achillea Millefolium L.)

open access: yesJournal of Natural Fibers, 2022
In this study, organic cotton knitting fabrics were dyed with yarrows (Achillea biebersteinii and Achillea millefolium L.). The fabric samples were separately dyed with flowers and leave-stems of yarrows – alum and yarrow – alum – gall oak.

FAST—Fast Algorithm for the Scenario Technique

open access: yesOperations Research, 2014
The scenario approach is a recently introduced method to obtain feasible solutions to chance-constrained optimization problems based on random sampling. It has been noted that the sample complexity of the scenario approach rapidly increases with the number of optimization variables and this may pose a hurdle to its applicability to medium- and large ...
