An immune genetic algorithm considering the velocity was brought forward, and the approach implements a real time solution to the problem. 針對具體問題，提出了一種免疫遺傳演算法，對演算法的快速性作出了考慮，滿足了求解的實時性要求。
First it used the information entropy theory to search the possible network structure quickly.Then, found out the best BN structure using the immune genetic algorithm. 首先，通過資訊理論迅速搜索較為可能的網路空間，構造一個候選網路，然後用免疫遺傳演算法進行網路精簡，得到一個最優的網路結構。
