In this article, we present the time-space Chebyshev pseudospectral method(TS-CPsM) to approximate a solution to the generalised Burgers-Fisher (gBF)equation. The Chebyshev-Gauss-Lobatto (CGL) points serve as the foundation forthe recommended method, which makes use of collocations in both the time andspace directions. Further, using a mapping, the non-homogeneousinitial-boundary value problem is transformed into a homogeneous problem, and asystem of algebraic equations is obtained. The numerical approach known asNewton-Raphson is implemented in order to get the desired results for thesystem. The proposed method's stability analysis has been performed. Differentresearchers' considerations on test problems have been explored to illustratethe robustness and practicality of the approach presented. The approximatesolutions we found using the proposed method are highly accurate andsignificantly better than the existing results.
