Abstract
In this paper, the approximation for stationary soliton solution with intersite-typed configuration in the cubic-quintic DNLS equation for anti-continuum limit is determined by a variational approximation (AV) method. The proposed ansatz is of the form an exponential function with three variational parameters. The obtained VA solutions are then examined its validation and compared with the corresponding numerical solutions. The results show that the VA solutions are valid and provide a very good agreement with the numeric.
