A new particle swarm optimization based on grey self-linkage analysis was presented. In order to overcome premature of standard particle swarm optimization, the proposed algorithm considered the interrelations between problem dimensions, which perform more frequent simultaneous updates on subsets of particle position components that are strongly linked and using new speed-location update formula....
The multi-criteria degree-constrained minimum spanning tree problem (mcd-MST) is an important issue in wireless sensor networks (WSNs) topology control. However, the multi-criteria MST (mc-MST) is NP-hard problem and mcd-MST is a typical mc-MST. In this paper, we present an improved discrete particle swarm optimization (PSO) approach for mcd-MST which gives a good compromise between many key objectives...
