Resource Overview
A Python program for generating Logistic Map bifurcation diagrams, demonstrating unique chaotic behavior distinct from conventional nonlinear systems. The mapping follows the equation: xₙ = 1 - a·xₙ₋₁², where parameter a ranges between 0 and 2. The implementation iterates through parameter values, discarding transients before plotting asymptotic behavior.
Detailed Documentation
This program generates a Logistic Map bifurcation diagram, revealing behavior patterns that differ significantly from typical nonlinear systems. The mathematical mapping is defined by the recurrence relation: xₙ = 1 - a·xₙ₋₁², where a is a real parameter in the interval [0,2].
Key implementation aspects include:
- Parameter sweeping through a-values with fine resolution
- Transient elimination by iterating initial conditions before recording data
- Bifurcation point visualization using scatter plots
- Chaotic regime detection through Lyapunov exponent calculations
