Underwater vehicles: The minimum time problem
- in Proc. IEEE Conf. Decision, Control
, 2004
"... Abstract — We consider the minimum time problem for a class of underwater vehicles. We focus on the situation of initial and final configurations at rest satisfying x0 6 = xf, z0 = zf, θ0 = θf = 0. We supplement our theory with a numerical study of optimal bang–bang and singular solutions and includ ..."

OPTIMIZING THE LINEAR QUADRATIC MINIMUM–TIME PROBLEM FOR DISCRETE DISTRIBUTED SYSTEMS
"... With reference to the work of Verriest and Lewis (1991) on continuous finite-dimensional systems, the linear quadratic minimum-time problem is considered for discrete distributed systems and discrete distributed time delay systems. We treat the problem in two variants, with fixed and free end points ..."

Uniqueness of Lower Semicontinuous Viscosity Solutions for the Minimum Time Problem
"... We obtain the uniqueness of lower semicontinuous (lsc for short) viscosity solutions of the transformed minimum time problem assuming that they converge to zero on a "reachable" part of the target in appropriate directions. We present a counter-example which shows that the uniqueness does ..."

Minimum Error Rate Training in Statistical Machine Translation
, 2003
"... Often, the training procedure for statistical machine translation models is based on maximum likelihood or related criteria. A general problem of this approach is that there is only a loose relation to the final translation quality on unseen text. In this paper, we analyze various training cri ..."

Finite-time analysis of the multiarmed bandit problem
- Machine Learning
, 2002
"... Abstract. Reinforcement learning policies face the exploration versus exploitation dilemma, i.e. the search for a balance between exploring the environment to find profitable actions while taking the empirically best action as often as possible. A popular measure of a policy’s success in addressing ..."

this dilemma is the regret, that is the loss due to the fact that the globally optimal policy is not followed all the times. One of the simplest examples of the exploration/exploitation dilemma is the multi-armed bandit problem. Lai and Robbins were the first ones to show that the regret for this problem has
Virtual time
- ACM Transactions on Programming Languages and Systems
, 1985
"... Virtual time is a new paradigm for organizing and synchronizing distributed systems which can be applied to such problems as distributed discrete event simulation and distributed database concur-rency control. Virtual time provides a flexible abstraction of real time in much the same way that virtua ..."
