Good random number generators are (not so) easy to find

Every random number generator has its advantages and deficiencies. There are no `̀ safe'' generators. The practitioner's problem is how to decide which random number generator will suit his needs best. In this paper, we will discuss criteria for good random number generators: theoretical support, empirical evidence and practical aspects. We will study several recent algorithms that perform bette...

Using Branch-and-Price to Find High Quality Solutions Quickly

When integer programming (IP) models are used in operational situations there is a need to consider the tradeoff between the conflicting goals of solution quality and solution time, since for many problems solving realistic-size instances to a tight tolerance is still beyond the capability of state-of-the-art solvers. However, by appropriately defining small instances, good primal solutions fre...

Easy lambda-terms are not always simple

A closed λ-termM is easy if, for any other closed termN , the lambda theory generated by M = N is consistent, while it is simple easy if, given an arbitrary intersection type τ , one can find a suitable pre-order on types which allows to derive τ forM . Simple easiness implies easiness. The question whether easiness implies simple easiness constitutes Problem 19 in the TLCA list of open problem...

Where to Find Information

Do older patients find multi-compartment medication devices easy to use and which are the easiest?

BACKGROUND multi-compartment medication devices (MMDs) are widely used, primarily by older people, to aid correct-medication taking. Several MMD types are available yet little is known about the ease with which patients with varying functional ability use these devices and whether some types are easier than others. Such knowledge would assist healthcare practitioners in advising patients on a s...
