bet365 best casino games Look at the two aspects of the knowledge of relative relationships and the reasoning of relative relationships，The existing relative relationship reasoning system lacks theoretical discussion on relatives and its form structure。Relations of relative relationships have complexity: The essence of relative relationship reasoning is the inference bet365 Play online games of blood relationship; the blood relationship structure is a "father"、"Mother"、"Child" to compose the recursive graph structure of the basic unit; the definition of relative relationships is given according to the shortest path in the blood relationship structure diagram; using the marriage relationship、Fertility relationship、Given relationship、Brothers and sisters relationship as four basic blood relationships，Reduce the expression of relative relationships; the use of relative relationships can determine the system boundary，and formally bet365 best casino games describes related concepts of relative relationships。Based on this，A relative relationship reasoning system based on blood relationship structure diagram is constructed，Use positioning、Matching、Retrieving the shortest path and displacement four operations，To complete the complex relative relationship reasoning task。Compared with the previous relative relationship reasoning system，The logic and steps of this reasoning system are more intuitive and concise，It guarantees the integrity and accuracy of the reasoning of relative relationship。A relative bet365 Play online games reasoning algorithm based on blood relationship can be promoted to other languages ​​relative relationship reasoning。
