2) pre-condition 前置条件 1. The method uses the pre-condition and post condition which the services must be met as a judge matching criteria,and this can speed up the matching of services and improve the matching accuracy,and prove the effectiveness of the method in the practical ...
Solution Pre-condition is x∈ℕ∧x>1. The post-condition is slightly more difficult to express. Clearly ab = x is a statement of the fact that a and b must multiply together to give x. Also a and b must be elements of ℕ. a and b cannot be 1 unless x is prime, this can ...

combining several (sub-) models from the repository into a new one specifically tailored for the task at hand. This paper proposes the determination of weakest precondition and postcondition (Hoare 1969; Dijkstra 1976; Backhouse 1985) for every process model in the repository to help solving this...
The qualitative rule generator based on cloud model is composed of the precondition cloud generator and the postcondition cloud generator. If a specific point a on the domain U1 is given, the certainty degree distribution of point a to concept C1 is generated through the cloud generator, then ...
