Abstract: The improved F-expansion is one of the furthermost effective algebraic methods for finding the exact travelling wave solutions of nonlinear evolution equations (NLEEs) in mathematical physics. In this paper, we seek out the new exact travelling wave solutions of (3 + 1)-dimensional potential Yu-Toda-Sasa-Fukuyama (YTSF) equation through the improved F-expansion method. The attained solutions are conveyed in terms of hyperbolic, trigonometric and rational functions including solitary and periodic solutions which have numerous prospective applications in physical science and engineering. In addition, the properties of these NLEEs are displayed with some figures.
