Hybrid Genetic Grey Wolf Algorithm for Large-Scale Global Optimization

Complex, 2019
Most real-world optimization problems tackle a large number of decision variables, known as Large-Scale Global Optimization (LSGO) problems. In general, the metaheuristic algorithms for solving such problems often suffer from the “curse of dimensionality.
