Taming chaos to sample rare events: the effect of weak chaos
Jorge C. Leitao, Joao M. V. P. Lopes, Eduardo G. Altmann
Rare events in non-linear dynamical systems are difficult to sample because of the sensitivity to perturbations of initial conditions and of complex landscapes in phase space. Here…
Efficiency of Monte Carlo Sampling in Chaotic Systems
Jorge C. Leitão, Eduardo G. Altmann, J. M. Viana Parente Lopes
In this paper we investigate how the complexity of chaotic phase spaces affect the efficiency of importance sampling Monte Carlo simulations. We focus on a flat-histogram simulatio…
Monte Carlo Sampling in Fractal Landscapes
Jorge C. Leitão, João M. Viana Parente Lopes, Eduardo G. Altmann
We propose a flat-histogram Monte Carlo method to efficiently sample fractal landscapes such as escape time functions of open chaotic systems. This is achieved by using a random-wa…
Effect of noise in open chaotic billiards
Eduardo G. Altmann, Jorge C. Leitão, João Viana Lopes
We investigate the effect of white-noise perturbations on chaotic trajectories in open billiards. We focus on the temporal decay of the survival probability for generic mixed-phase…
