In this communication we undertake a performance analysis for a new class of evolutionary algorithms
called chaos optimization algorithm (COA), recently proposed by Caponetto and al. [1], [2], [3], It was
originally proposed to solve nonlinear optimization problems with bounded variables. Dierent chaotic
mapping have been considered, combined with several working strategy. In this work, a chaotic strategy
is proposed based on a new two-dimensional discrete chaotic attractor.Experiments results showed that
the proposed algorithm can achieve good performance.
