“…There are many techniques that can be used to solve the clustering problem. In our study the clustering problem was solved by using the PSO algorithm (Kennedy and Eberhart 1995; Poli, Kennedy, and Blackwell 2007; Correa, Freitas, and Johnson 2008; Durán, Rodriguez, and Consalter 2008; Arumugam, Rao, and Tan 2009; DeBao and ChunXia 2009). A new population‐based stochastic algorithm, PSO, introduced by Kennedy and Eberhart (1995), is considered as one of the modern heuristic algorithms for optimization.…”
