摘要

The magnitude of the largest Lyapunov exponent (LE) is used as a metric of chaoticity. The Kaplan-Yorke dimension is utilized to measure the complexity of a hyperchaotic system. A system having higher largest Lyapunov exponent has more chaoticity, and a higher Lyapunov dimension exhibits more complexity. We have performed a comparative analysis considering six different hyperchaotic systems to kno...
