## Abstract

A continuum growth equation in 1+1 dimensions is obtained by considering the contributions to the underlying current from kinetics of adatoms on the surface. These considerations reproduce the slope dependent term that represents a stable or an unstable growth depending on the sign of the associated coefficient. In addition an h to -h symmetry breaking nonlinear term is obtained. Implications of this term on stable to unstable transition are discussed. This term is tilt independent and is expected to be present independent of the source of the current in the conserved growth. Computer simulation based on a zero diffusion bias model is used to verify some of the predictions of the minimal growth equation. It is shown that the growth equations for cellular automata type models involving instantaneous relaxations can be obtained from the proposed method by addressing the corresponding kinetics of adatoms.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
