A schemata theorem for trees
نویسنده
چکیده
The proof of a schemata theorem for trees of bounded branching with a probabilistic crossover is sketched. The argument presented applies only to the case where the genetic information is placed at the terminal nodes of the tree although the shape of the tree itself can be considered as an additional form of genetic information.

The basic Schema Theorem for genetic algorithms is modiied for a grammatically-based learning system. A context-free grammar is used to deene a language in which each sentence is mapped to a tness value. The derivation trees associated with these sentences are used to deene the structure of schemata. The eeect of crossover and mutation on schemata is described. A schema theorem is developed whi...
متن کاملA Resolution Calculus for Recursive Clause Sets [Preprint]
Proof schemata provide an alternative formalism for proofs containing an inductive argument, which allow an extension of Herbrand’s theorem and thus, the construction of Herbrand sequents and expansion trees. Existing proof transformation methods for proof schemata rely on constructing a recursive resolution refutation, a task which is highly non-trivial. An automated method for constructing su...

متن کاملSchemata as Building Blocks: Does Size Matter?
We analyze the schema theorem and the building block hypothesis using a recently derived, exact schemata evolution equation. We derive a new schema theorem based on the concept of eeective tness showing that schemata of higher than average eeective tness receive an exponentially increasing number of trials over time. The building block hypothesis is a natural consequence in that the equation sh...
متن کاملSchemata Evolution and Building Blocks
In the light of a recently derived evolution equation for genetic algorithms we consider the schema theorem and the building block hypothesis. We derive a schema theorem based on the concept of effective fitness showing that schemata of higher than average effective fitness receive an exponentially increasing number of trials over time. The equation makes manifest the content of the building bl...
