摘要: 模式定理是遗传算法的重要理论结果.一般的模式定理只讨论了模式存活的概率而没有考虑模式新建的概率.讨论在模式的存活和新建的共同作用下的模式定理,提出了几个基础概念——子模式、互补模式、模式的存活和模式的新建,给出了在模式的存活和新建共同作用下的模式定理,它深入和推广了目前模式定理的结果.

Abstract: Schema theorems are important theoretical results in genetic algorithms. However, the general schema theorems only discuss the probability of the survival of schemas, but do not discuss the probability of the construction of schemas. In this paper we discuss the schema theorems affected by both the survival and the construction of schemas. First, some basic concepts including the subschema, the complementary-schema, the survival and the construction of schema are introduced, and then the schema theorems affected by both the survival and the construction of schemas are proposed. They are generalizations and extensions of the existing schema theorems.

Key words: genetic algorithm, schema theorem, uniform recombination
