Group search optimizer with intraspecific competition and lévy walk

This short communication presents a nature-inspired optimization algorithm, group search optimizer with intraspecific competition and lévy walk (GSOICLW). The mechanism of intraspecific competition (IC) and the searching strategy of lévy walk (LW) are incorporated to the original group search optimizer (GSO) algorithm. It has been proved that GSOICLW shows a significant improvement to GSO after its test against standard benchmark functions.
