摘要

In this paper, the local derivative in time is replaced with the Caputo-Fabrizio fractional derivative of order α∈2 (0, 1). A two-step fractional version of the Adams-Bashforth method is formulated for the approximation of this derivative. To enhance the correct choice of parameters when numeri- cally simulating the full-system, we examine the stability analysis of the main equation. Two important examples are drawn to explore the dynamic richness of the predator-prey model with Holling type. Simulation results at different instances of α is in agreement with the theoretical findings.
