Comments on "simple chaotic flows with a line equilibrium" [chaos, solitons & fractals 57 (2013) 79-84]

Abstract

In the above paper, the authors proposed a search algorithm for finding simple chaotic systems with quadratic nonlinearities which have the unusual feature of having a line equilibrium and introduced nine novel chaotic flows. However, the equations of 4th-9th chaotic flows were incorrectly given. In this letter, the correct equations are presented for the future usage of these line equilibrium chaotic flows.
