چکیده

We use genetic algorithms (GAs) to nd good nite horizon policies for POMDPs, where the search is limited to policies with a xed nite amount of policy memory. Initial results were presented in (Lusena et al. 1999) with one GA. In this paper, diierent cross-over and mutation rates are compared. Initializing the population of the genetic algorithm is done using smaller genetic algorithms. The selection and termination criteria are altered and tested. Reordering and uniform cross-over are implemented and compared against the original GA. And nally, a steady-state GA is implemented and used as a control for tests with a steady-state GA whose operator rates are dynamic.

Approximating the step change point of the process fraction non conforming using genetic algorithm to optimize the likelihood function

Control charts are standard statistical process control (SPC) tools for detecting assignable causes. These charts trigger a signal when a process gets out of control but they do not indicate when the process change has begun. Identifying the real time of the change in the process, called the change point, is very important for eliminating the source(s) of the change. Knowing when a process has ...

A New Approach to Solve N-Queen Problem with Parallel Genetic Algorithm

Over the past few decades great efforts were made to solve uncertain hybrid optimization problems. The n-Queen problem is one of such problems that many solutions have been proposed for. The traditional methods to solve this problem are exponential in terms of runtime and are not acceptable in terms of space and memory complexity. In this study, parallel genetic algorithms are proposed to solve...

Monte Carlo Sampling Methods for Approximating Interactive POMDPs

Partially observable Markov decision processes (POMDPs) provide a principled framework for sequential planning in uncertain single agent settings. An extension of POMDPs to multiagent settings, called interactive POMDPs (I-POMDPs), replaces POMDP belief spaces with interactive hierarchical belief systems which represent an agent’s belief about the physical world, about beliefs of other agents, ...

Optimal Cost Almost-Sure Reachability in POMDPs

We consider partially observable Markov decision processes (POMDPs) with a set of target states and every transition is associated with an integer cost. The optimization objective we study asks to minimize the expected total cost till the target set is reached, while ensuring that the target set is reached almost-surely (with probability 1). We show that for integer costs approximating the opti...

A Particle Filtering Based Approach to Approximating Interactive POMDPs

POMDPs provide a principled framework for sequential planning in single agent settings. An extension of POMDPs to multiagent settings, called interactive POMDPs (I-POMDPs), replaces POMDP belief spaces with interactive hierarchical belief systems which represent an agent’s belief about the physical world, about beliefs of the other agent(s), about their beliefs about others’ beliefs, and so on....
