This paper studies the fundamental problems of mining association rules. Based on the summary of classical mining algorithm and the inherent defects of Apriori algorithm, some related improvements are researched. In order to avoid scanning the database multiple times, the database mapping method is changed in this research. Meanwhile, after the support of candidate item sets is get, each candidate...
In order to predict the dynamic surface subsidence and deformation, a working face was divided into some mining elements along strike according to the face advancing, and the dynamic surface subsidence and deformation was regard as the superposition of the dynamic subsidence and deformation independently of all these mining elements. There might be a section of which width was shorter than a mining...
Negotiation strategy is an important research branch of agent-based automatic negotiation. Under the background of bilateral multi-issues negotiation, a novel negotiation skill algorithm by interactive micro-adjustment and multi-rounds approximation is proposed, which classifies both partiespsila proposal issues into two divisions --- interest point set and disinterest point set, and combined with...
