一种可破解permutation-only图像加密算法的通用方法，使用cat，baker等置乱方法加密的图像可成功被破解。-One kind of permutation-only image can crack the encryption algorithm common method using cat, baker and other image scrambling encryption method can be successfully cracked.

In this paper, we present a new algorithm of swarm intelligence, namely, Cat Swarm Optimization (CSO). CSO is generated by observing the behaviors of cats, and composed of two sub-models, i.e., tracing mode and seeking mode, which model upon th
