This chapter introduces the application of an improved particle swarm algorithm to pin connected space structures. The algorithm is named harmony particle swarm optimization (HPSO), as it is based on harmony search schemes and the standard particle swarm algorithm. The efficiency of HPSO for pin connected structures with different variable types including continuous variables and discrete variables is compared with that of other intelligent algorithms, and the implementation of HPSO is presented in detail. An optimal result of a complex practical double-layer grid shell structure is presented to value the effectiveness of the HPSO.
