“…The TLBO algorithm has already been successfully applied by various researchers for solving complex benchmark functions and difficult engineering problems (Azizipanah-Abarghooee et al 2012, Hosseinpour et al 2011, Krishnanand et al 2011, Nayak et al 2011, Niknam et al 2012a, Rao and Kalyankar 2012a, Rao and Savsani 2012, Rao and Patel 2012a2012d, Satapathy and Naik 2011, Satapathy et al 2012, Toğan 2012. Contrary to the opinion expressed by Črepinšek et al (2012) that TLBO is not a parameter-less algorithm, this paper has clearly explained that TLBO is an algorithm-specific parameter-less algorithm and this was already stated by Rao and Patel (2012a).…”
