Kardar-Parisi-Zhang interface growing equation with different noise terms

The Kardar-Parisi-Zhang interface growth equation with the initial condition cos (x4) has been studied with 4 Gaussian noise term and without noise term. In the latter case, the lowest-order nonlinear term of the Kardar-Parisi-Zhang equation parameters was chosen between 0.1 and 2 for v and λ = 0.1. These two different parameter values provided more accurate change detection in terms of initial state and noise differences.
