With the wide application of Internet technology,network information transmission technology is also developing rapidly,and the demand for network transmission anomaly detection is increasing year by year.Aiming at the problems of low operation speed,low detection rate and large error of current network transmission anomaly detec⁃tion algorithms,this paper proposes a dense space network transmission anomaly detection algorithm based on heuris⁃tic algorithms.Firstly,the backpropagation algorithm was used to optimize the basic detection principle.Secondly,the feature of abnormal data was extracted based on the time decay function.Thirdly,the network transmission anom⁃aly detection algorithm model was designed based on a heuristic genetic algorithm.Finally,the adaptive parameters of the genetic algorithm were optimized.The algorithm uses the network database for experiments.The experimental re⁃sults show that compared with other anomaly detection methods,the proposed algorithm reduces the false detection rate by nearly 10%and the missed detection rate by at least 7%,greatly reducing the impact of network transmission anomalies,promoting the research of heuristic genetic algorithm,and promoting the development and application of network transmission anomaly detection technology.
