说明：  麻雀搜索算法(Sparrow Search Algorithm, SSA)是于2020年提出的。SSA 主要是受麻雀的觅食行为和反捕食行为的启发而提出的。该算法比较新颖，具有寻优能力强，收敛速度快的优点(Sparrow search algorithm (SSA) was proposed in 2020. SSA is mainly inspired by the foraging behavior and anti predation behavior of sparrow. The algorithm is novel and has the advantages of strong optimization ability and fast convergence speed)
