“…In [22], the authors have reviewed different variants, applications of CSO as well as efficacy of CSO in solving different real-world problems. For example, CSO is applied for solving economic load dispatch [23], fault diagnosis of pumping wells [24], ascent trajectory optimization [25], train energy saving [26], robot path planning [27] etc. Similarly, TLBO is successfully used to cope with parameter optimization of machining process [28], transmission expansion planning [29], economic load dispatch problem [30], optimization of heat exchangers [31], optimal configuration of microgrid [32], optimization of space trusses [33], groundwater prediction [34], energy demand estimation [35], parameter extraction of photovoltaic models [36], glazing system design [37], PID controller design [38], wind speed forecasting [39], energy performance assessment of buildings [40], etc.…”
