“…Then, they explored previously conducted eight benchmark-function-based comparative studies (namely, unconstraint optimization [Storn and Price 1997b;Paterlini and Krink 2004;Vesterstroem and Thomsen 2004;Ali and Törn 2004], multi-constraints nonlinear optimization [Lampinen 2004], mixed-variable optimization [Lampinen and Zelinka 1999b], multi-objective optimization [Kukkonen and Lampinen 2004], noisy-function optimization ) and also eleven application-oriented performance comparison studies (namely, multi-sensor fusion [Joshi and Sanderson 1999], earthquake relocation [Bohuslav and Michal 2001], DC operating point analysis for nonlinear circuits [Crutchley and Zwolinski 2004], estimation of heat transfer parameters in a trickle-bed reactor [Babu and Sastry 1999], aerodynamic optimization [Rogalsky et al 1999], image registration [Salomon 2001], identifying induction motor parameters [Ursem and Vadstrup 2004], optimization of neural networks [Fischer et al 1999;Plagianakos et al 2001], and optimization of carbon and silicon cluster geometry [Ali and Törn 2000;Chakraborti et al 2002]). Finally, they concluded as follows:…”
