abstract = "The basic Schema Theorem for genetic algorithms is
modified for a grammatically-based learning system. A
context-free grammar is used to define a language in
which each sentence is mapped to a fitness value. The
derivation trees associated with these sentences are
used to define the structure of schemata. The effect of
crossover and mutation on schemata is described. A
schema theorem is developed which describes how
sentences of a language are propagated during
evolution.",
