Tent chaotic map
Web9 Mar 2015 · 1. Although your formulae are technically correct, you will not get the expected plot if you were to plot this function. The reason is that you increment along the x-axis in steps of 1 (in the for loop), and the width of the entire tent map function from the link you provided is 1. Therefore, only the first 2 points in your function are useful. Webchaotic_maps. A python library for creating cobweb plots, bifurcation diagrams, and calculating the Lyapunov exponents of one-dimensional maps. The library includes several common one-dimensional maps and discrete-time evolutionary/learning dynamics such as the replicator dynamic.
