Ultra-chaos: an insurmountable objective obstacle of reproducibility and replicability
Shijun Liao, Shijie Qin
In this paper, a new concept, i.e. ultra-chaos, is proposed for the first time. Unlike a normal-chaos, statistical properties such as the probability density functions (PDF) of an…
Influence of database noises to machine learning for spatiotemporal chaos
Yu Yang, Shijie Qin, Shijun Liao
A new strategy, namely the "clean numerical simulation" (CNS), was proposed (J. Computational Physics, 418:109629, 2020) to gain reliable/convergent simulations (with negligible nu…
Three-body problem -- from Newton to supercomputer plus machine learning
Shijun Liao, Xiaoming Li, Yu Yang
The famous three-body problem can be traced back to Newton in 1687, but quite few families of periodic orbits were found in 300 years thereafter. In this paper, we propose an effec…
Accurate predictions of chaotic motion of a free fall disk
Tianzhuang Xu, Jing Li, Zhihui Li +1
It is important to know the accurate trajectory of a free fall object in fluid (such as a spacecraft), whose motion might be chaotic in many cases. However, it is impossible to acc…
