Optimization Computation in Dynamic Hierarchical System

In this paper, DNAS, a system for utilizing computer resources that exist in distributed manner is proposed. DNAS uses tree structure for communication topoogy between nodes. We implemented optimization methods, such as genetic algorithm and random search on this system. Random search improved search time with increase in number of nodes. For genetic algorithm, search time improved with increase in node number, but the result was not as good as it was expected.
