Horizontal visibility graphs

Webcomplexity as the state-of-the-art natural visibility graphs computation, but it represents a substantial improvement for the computation of horizontal visibility graphs. A. Encoding—Maximum binary search tree The construction of a maximum binary search tree is fairly straightforward, and its corresponding pseudocode is shown in Algorithm 1. Webingly, the horizontal visibility graph associated with any ran-dom series is a small-world 10 random graph with a uni-versal exponential degree distribution of the form P k = 1/3 2/3 k−2, independent of the probability distribution f x from which the series was generated. Accordingly, the horizontal visibility algorithm stands as an extremely ...
