“…In particular, the stability theory of the solution of conformable fractional-order nonlinear deterministic and stochastic systems has attracted much more attention (see [6], [7], [8], and [9]). Recently, it has established its effectiveness as an important tools in many fields applications, such as control theory [6,7,[9][10][11][12][13][14][15], physics [16], or biology [8,17,18]. In fact, Neirameh in [8] suggested a method to find exact solitary wave solutions of extended biological population model.…”
