This is the matlab code for Chaotic Kbest Gravitational Search Algorithm (CKGSA). This variant uses the chaotic model for Kbest parameter to balance the exploration and exploitation non-linearly in the Gravitational Search Algorithm (GSA) and results are promising.
The code is based on the research paper. Link: http://ieeexplore.ieee.org/document/7880252/
