Schemata as Building Blocks: Does Size Matter?
C. R. Stephens, H. Waelbroeck, R. Aguirre
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…
Schemata Evolution and Building Blocks
C. R. Stephens, H. Waelbroeck
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 t…
A Hamiltonian Lattice Theory for Homogeneous Curved Spacetimes in 2+1 Dimensions
A. Criscuolo, H. Waelbroeck
We propose an exact Hamiltonian lattice theory for (2+1)-dimensional spacetimes with homogeneous curvature. By gauging away the lattice we find a generalization of the ``polygon re…
Quantization of 2+1 Gravity on the Torus
A. Criscuolo, H. Quevedo, H. Waelbroeck
We use the polygon representation of 2+1--dimensional gravity to explicitly carry out the canonical quantization of a universe with the topology of a torus. The mapping-class-invar…
