abstract = {Tunnel crossing problem is unavoidable in the development of the topic crawler. To solve this problem, a self-decision topic crawler algorithm based on Boyd loop (FCIDOL) was proposed. The algorithm took the Boyd loop as the basic framework and formed a closed loop according to the principle of “observation-assessment-decision-action”. According to the work completed by the crawler, which refers to memory, the algorithm evaluated the current state observed to generate decisions of radical or conservative strategies, guiding the crawler to search for new theme-relevant web pages or to focus on the actions of short-term benefits. The role of memory was to provide training materials for the assessment network, thus realizing the online training of the network to meet the cold start of the crawler. The experiment shows that compared with various topic crawler algorithms in different topic environments, FCIDOL achieves an improvement of over 7.8% in harvest rate, and the number of duplicate links is reduced by more than 15.6%.}
