  Randomness and parameter selection in the Particle Swarm Optimization (PSO) algorithm had great influence on its performance. This study presented a formal convergence and spectral radius analysis of the standard PSO algorithm model, where some of the parameters were stochastic. Based on the analysis of the relationship of {ω, c1, c2}, a sufficient condition was given to guarantee that the PSO algorithm was mean-square convergent, using the stochastic process theory. Then, the mean spectral radius was constructed. According to the relationship between the spectral radius and the convergent speed, it was shown that, a small spectral radius lead to a faster convergent speed than a big one. By optimizing the mean spectral radius of the PSO algorithm in the mean-square convergent region, a minimum spectral radius and corresponding parameter selection guidelines were derived to guarantee that the PSO algorithm was mean-square convergent and had a fast convergent speed in the stochastic sense. Finally, one parameter selection {c1 = c2 = 2, ω = 0.4222} was proposed. with the parameter, the study gave examples whose performance on benchmark functions were superior to previously published results.

  Security issues are increasingly obvious. An automated real-time online alarm system to ensure the safety of property and personality while considering numerous smart Terminal Equipments (TE) becomes a major challenge. At the same time, this is representative of novel and emerging alarm system for assisted living in the daily life. Two problems of current alarm system are identified. A smart Cyber-Physical Alarm System (CPAS) based approach is proposed to address these problems. A prototype system installed in a house to assist living has been running stably and shows quite promising performance.
