Randomized allocation processes

Random Structures & Algorithms, 2001
AbstractMany dynamic resource allocation and on‐line load balancing problems can be modeled by processes that sequentially allocate balls into bins. The balls arrive one by one and are to be placed into bins on‐line without using a centralized controller.

Presenting Objects for Random Allocation

SSRN Electronic Journal, 2022
AbstractFor random allocation, whether a desirable rule exists or not hinges on the domain of agents' preferences, whose formation is affected by how objects are presented. We hence propose a model studying how to present objects so that the induced preference domain allows for designing a good rule.

Random allocation II

BMJ, 2009
A randomised single blind controlled trial investigated whether pelvic floor muscle training during pregnancy prevented urinary incontinence during and after pregnancy. The trial recruited healthy nulliparous women when they attended their first routine ultrasound.

Random allocations and probabilistic languages

1988
This paper introduces a unified framework for the analysis of a class of random allocation processes that include: (i) the birthday paradox; (ii) the coupon collector problem; (iii) least-recently-used (LRU) caching in memory management systems under the independent reference model; (iv) the move-to-front heuristic of self-organizing search.

Random Arc Allocation and Applications

2002
The paper considers a generalization of the well known random placement of balls into bins. Given n circular arcs of lengths ?1, ..., ?n we study the maximum number of overlapping arcs on a circle if the starting points of the arcs are chosen randomly. We give almost exact tail bounds on the maximum overlap of the arcs.

Controlled trials: allocation concealment, random allocation, and blinding

BMJ, 2015
The efficacy of nicotine patches in pregnant women who smoke was investigated using a randomised placebo controlled trial. The intervention was the administration of 16 hour nicotine patches until the time of delivery. Participants were 402 pregnant women older than 18 years who smoked at least five cigarettes a day and whose babies were between 12 and

Randomization. Part 3: Allocation concealment and randomization implementation

American Journal of Orthodontics and Dentofacial Orthopedics, 2012
Randomization consists of 3 steps: generation of the random allocation sequence, allocation concealment, and implementation of the random allocation sequence. In the previous 2 articles, we discussed the methods to generate the random allocation sequence (the Table summarizes these methods); in this final article on randomization, we will discuss ...

A Resource Allocation Problem in a Random Environment

Operations Research, 1989
We consider a resource allocation problem in which various parameters of the model change according to independent random environment Markov processes. There are a finite number of activities that each require a resource, and resources arrive according to a Poisson process.

Random sampling versus random allocation

BMJ, 2011
Researchers investigated the effects of providing people with evidence based information about colorectal cancer and screening. A randomised controlled study design was used. The intervention was a brochure that included personalised risk of colorectal cancer, available screening options with possible benefits and harm, plus information on prevention ...
