Over the past few decades, there has been a significant and rapid expansion in research related to nonlinear phenomena. The application of advanced methods for obtaining exact real solutions to partial differential equations (PDEs) and systems of such equations has become a focal point of active investigation in both mathematics and the applied sciences. These methods are specifically designed to deliver precise solutions to PDEs, which are essential for understanding a wide range of complex phenomena and addressing various scientific problems. However, despite the progress in nonlinear dynamics, there is still no universal method available for solving all types of nonlinear PDEs. This means that finding nonlinear wave solutions often requires tailored approaches, addressing each specific equation individually. In this study, we investigate a generalized reaction-diffusion model, which describes the spatiotemporal dynamics of interacting agents. This model incorporates several novel features when compared to classical models in population dynamics, offering new insights into the interactions between agents in the system. Various analytical techniques have been developed to find wave solutions to PDEs. In this research, we apply a particular variant of the recently developed Simple Equations Method (SEsM), specifically the Modified Simplest Equation Method, along with one of its extended versions. By using this approach, we are able to obtain a new traveling wave solution for the system under consideration. Numerical simulations of this solution reveal the propagation of nonlinear waves within the model. The characteristics of the traveling wave solution are then visualized, and their implications are discussed in detail, providing a deeper understanding of the dynamics within the system.
