Unstructured P2p

In this paper we focus on replication method in unstructured Peer-to-Peer (P2P) networks. Most current replication approaches are designed for the structured P2P systems. The EAD is specific for the unstructured P2P network, but the replica utilization is low and has the bump problem. In order to acquire more replica utilization and search efficiency, we propose a decentralized replication methodsFTR. The proposed algorithm can calculate the real query flow of node according to the order of the node selected. Experiment on the simulation proves that our method can enhance search success rate and replica hit rate.

Loading Problem

The paper is focused on the Multi-cargo Loading Problem (MCLP). Tabu search algorithm is an algorithm based on neighborhood search. According to the features of the problem, the essay centered the construct initial solution to construct neighborhood structure. For the operation, 1-move and 2-opt were applied, it can also fasten the speed of convergence, and boost the search efficiency. Finally, the good performance of this algorithm can be proved by experiment calculation and concrete examples.
