Stochastic Optimization for a Class of Hierarchical Unstructured P2P System
Chenfeng Xu, Hongsheng Xi, Qi Jiang, Baoqun Yin · 2006
For a class of hierarchical unstructured P2P systems, a Markov Switching-Space model is introduced to describe their behavior of dynamic grouping. It is also formulated as a optimization problem based on Markov Decision Processes. And parameterized gradient algorithms are provided to optimize the performance, where two parameter reductions are mentioned. Following them are the corresponding simulations and discussions.
