Web3. Tent mapping-Chaotic Equation Here in this paper we are dealing with the Tent mapping. A deal of chaotic behaviour can be described by one simple, fairly innocuous looking equation, the Tent map as shown in the Figure1.,and the bifurcation for the tent map in Figure 2. The chaotic mapping is as follows WebA. Tent Map The simplest chaotic process is the tent map. Pick a number xo between 0 and 1. Then generate the sequence of numbers xt using the following rule: xt= 2xt_1, if xt-1 < 0.5, x= 2(1 - xt_), if xt1 > 0.5. (1) The tent map is so named because the graph of xt versus xt- 1 is shaped like a "tent", as shown in Figure 1. Web23 Jan 2024 · In some areas the tent map equation is used to generate chaotic sequence, here t(n) = x(n+1). The equation would turn into x(n+1) = (x(n))/c for 0 ≤ x(n) < c and x(n+1) = (1-x(n))/(1-c) for c ≤ x(n) ≤ 1. Why the equation is stated differently? So the value of x(n+1) will never exceed 1. For example if “c = 0.4” and “x = 0.5” and ... glass bunny jars wholesale
