Stochastic recursive inclusion in two timescales with an application to the Lagrangian dual problem
In this paper we present a framework to analyze the asymptotic behavior of
two timescale stochastic approximation algorithms including those with
set-valued mean fields. This paper builds on the works of Borkar and Perkins &
Leslie. The framework presented herein is more general as compared to the
synchronous two timescale framework of Perkins \& Leslie, however the
assumptions involved are easily verifiable. As an application, we use this
framework to analyze the two timescale stochastic approximation algorithm
corresponding to the Lagrangian dual problem in optimization theory
How to conduct research in an independent hospice: practical tips and advice
Independent hospices can – and should aim to – participate in palliative care research, say Paul Perkins, Rebecca Day, Julie Hapeshi, Lorraine Dixon and Rudo Nyakuhwa, who give tips and advice based on their experience at Sue Ryder
