“…Meanwhile, although computation power has grown exponentially and mathematical models are much more complex than those in early work, the basic problems of considering strict constraints and unreliable assumptions still remain. To solve these problems, multidisciplinary efforts are needed, such as efficient solution schemes for FADEs on which efforts have been devoted by many experts (Baeumer et al, 2018; Cartalade et al, 2019; Hajipour et al, 2019; Hussain & Haq, 2019; Jannelli et al, 2019; X. T. Liu, Sun, Zhang, & Fu, 2019; X. T. Liu, Sun, Zhang, Zheng, & Yu, 2019; Wei, Chen, Zhang, Wei, & Garrard, 2018; Yi & Sun, 2019; Yu et al, 2018).…”
