Abstract: To improve classic visibility algorithm of transformation from time series to complex networks, this paper proposes maximum value split algorithm and convex hull algorithm and applies them in the fractal Brown time series respectively. Experimental results show that improved algorithm can reduce time complexity remarkably.

Key words: time series, visibility algorithm, maximum value split, convex hull
