A novel swarm intelligence optimization approach: sparrow search algorithm
TL;DR: A novel swarm optimization approach, namely sparrow search algorithm (SSA), is proposed inspired by the group wisdom, foraging and anti-predation behaviours of sparrows, which shows that the proposed SSA is superior over GWO, PSO and GSA in terms of accuracy, convergence speed, stability and robustness.
