We define the analytical graph from which we deduce a series of properties and obtain a theorem for evaluating the set of keys in relational schema.
我们定义了分析图,推导了一系列性质,并由此得到关系模式的关键字集的求解定理。

At last, an important theorem, Fuzzy Schematheorem, is given.
还给出了一个重要的定理:模糊模式定理。

It proves a schematheorem for genetic algorithms in which representation schema is based on graph grammar. The effect of crossover and mutation on schemata is described.
