Tuning approximate dynamic programming policies for ambulance redeployment via direct search

open access: yesStochastic Systems, 2014
In this paper we consider approximate dynamic programming methods for ambulance redeployment. We first demonstrate through simple examples how typical value function fitting techniques, such as approximate policy iteration and linear programming, may not

Direct search methods: then and now

open access: yesJournal of Computational and Applied Mathematics, 2000
The authors discuss direct search methods for unconstrained optimization. They discuss how direct search methods are characterized by the absence of the construction of a model of the objective. The article is informative and well-written. It makes a rather pleasant introduction to a very active survey area.
