Group Search Optimizer: An Optimization Algorithm Inspired by Animal Searching Behavior
This algorithm was written based on the work by He, S., Wu, Q.H. and Saunders, J.R.: He, S., Wu, Q. H., & Saunders, J. R. (2009). Group Search Optimizer: An Optimization Algorithm Inspired by Animal Searching Behavior. IEEE Transactions on Evolutionary Computation, 13(5), 973-990. doi: 10.1109/TEVC.2009.2011992.
