Exploring an alternative cellular avalanche model based on the maximum release of energy during solar flares, this research delves into optimizing models to study the quasi-static evolution of coronal magnetic fields. Through a series of image objects and studies, the study presents various cellular automaton avalanche models and their implications for understanding solar flares and complex behavior in a dynamic system. Key developments and models discussed include those by Lu, Hamilton, Georgoulis, Vlahos, Norman, Strugarek, Charbonneau, Joseph, and Pirot, shedding light on the deterministically-driven model and its significance.
