Di Luo, Jian Hua Chen, Qing Qing Wang, Ran Hou · Advanced materials research · 2014
In this paper, the optimization of context weighting coefficients are studied and the objective of the optimization is to find a group of weighing coefficients, such that the code length ofsource symbols occurred before the current symbol can be minimized. Multivariant optimization algorithm is used to find the solution of this multimodal optimization problem. With this context weighting algorithm, the compression efficiency is improved.
