零相移滤波器m函数，优点是克服了滤波器产生的相位滞后，缺点是本仿真不能保证实时性，其原理为输入一次序列，正反各变换一遍。(Zero phase shift filter m function, the advantages of the filter to overcome the phase lag, the disadvantage is that the simulation can not guarantee real-time, the principle of the input sequence, the pros and cons of each conversion.)

说明：  his work proposes two novel optimization algorithms called Salp Swarm Algorithm (SSA) and Multiobjective Salp Swarm Algorithm (MSSA) for solving optimization problems with single and multiple objectives. The main inspiration of SSA and MSSA is the swarming behaviour of salps when navigating and foraging in oceans. These two algorithms are tested on several mathematical optimization functions to observe and confirm their effective behaviours in finding the optimal solutions for optimization problems.
