Abstract


Two kinds of methods (graphical and statistical) commonly used for the estimation of fractal dimension of self-avoiding interfaces were investigated. It was determined that the current methods of both kinds have significant errors for this type of profiles. In the present work a novel efficient method for the estimation of fractal dimension of self-avoiding curves embedded in the space $\mathbb{R}^2$ based on the Box-count and Hall-Wood estimators is developed. Some physical implications are discussed.
