Spam has brought serious negative impact on people's life today. Many filtering methods have been proposed, but less perfect. In this essay, a detection model based on simulated annealing algorithm and sending behavior is presented to cover some shortcomings of the existing methods.Simulated annealing algorithm can find the global optimal solution, and the convergence is strong, and the spam detection technology based on sending behavior can significantly improve the speed of the server to deal with spam. Through experiments,the recall rate of...
