Abstract. This paper presents the formulation of the time-fractional Degasperis-Procesi equation using the Euler-Lagrange variational technique in the Riemann-Liouville derivatives sense and derives an approximate solitary wave solution. Our results witness that He's variational iteration method was very efficient and powerful technique in finding the solutions of the proposed equations.
