Henry Saxon Snell Prize

Maternity Homes: The Henry Saxon Snell Prize

Sir,-?I desire to draw the attention of your readers to the subject set for this prize for the current year, viz., " A Maternity Home and Infant Welfare Centre." In the cause of social progress, these institutions are bound to have an importance in the future which is as yet little realised. Although a comparatively small number of specially designed buildings have been erected (and these are, ...

Saxon: an Extensible Multimedia Annotator

This paper introduces Saxon, a rule based document annotator that is capable of processing and annotating several document formats and media, both within and across documents. Furthermore, Saxon is readily extensible to support other input formats due to both it’s flexible rule formalism and the modular plugin architecture of the Runes framework upon which it is built. In this paper we introduc...

Snell envelope with small probability criteria

We present a new algorithm to compute the Snell envelope in the specific case where the criteria to optimize is associated with a small probability or a rare event. This new approach combines the Stochastic Mesh approach of Broadie and Glasserman with a particle approximation scheme based on a specific change of measure designed to concentrate the computational effort in regions pointed out by ...

On the Robustness of the Snell Envelope

We analyze the robustness properties of the Snell envelope backward evolution equation for the discrete time optimal stopping problem. We consider a series of approximation schemes, including cut-off type approximations, Euler discretization schemes, interpolation models, quantization tree models, and the Stochastic Mesh method of Broadie-Glasserman. In each situation, we provide non asymptotic...
