A Grammar-Based Technique For Genetic Search And Optimization, Clayton Matthew Johnson
A Grammar-Based Technique For Genetic Search And Optimization, Clayton Matthew Johnson
Dissertations, Theses, and Masters Projects
The genetic algorithm (GA) is a robust search technique which has been theoretically and empirically proven to provide efficient search for a variety of problems. Due largely to the semantic and expressive limitations of adopting a bitstring representation, however, the traditional GA has not found wide acceptance in the Artificial Intelligence community. In addition, binary chromosones can unevenly weight genetic search, reduce the effectiveness of recombination operators, make it difficult to solve problems whose solution schemata are of high order and defining length, and hinder new schema discovery in cases where chromosome-wide changes are required.;The research presented in this dissertation …
A Bipartite Model Of Distributed Systems: Possibilities And Implications, Anna Karin Brunstrom
A Bipartite Model Of Distributed Systems: Possibilities And Implications, Anna Karin Brunstrom
Dissertations, Theses, and Masters Projects
Networking software is generally designed in layers. User processes exist at the application layer. They rely on the transport layer to provide them with end-to-end communication. In the distributed systems literature communication is traditionally viewed from the application layer. at the application layer we have no knowledge of the whereabouts of a message once a send operation is completed. at the transport layer, on the other hand, information about the delivery of a message to the transport layer in the receiving host is often available. We believe transport layer information can be better utilized in distributed systems design. This dissertation …

Analysis Of (Iso)Surface Reconstructions: Quantitative Metrics And Methods, Tracey Allen Beauchat
Dissertations, Theses, and Masters Projects
Due to sampling processes volumetric data is inherently discrete and most often knowledge of the underlying continuous model is not available. Surface rendering techniques attempt to reconstruct the continuous model, using isosurfaces, from the discrete data. Therefore, it natural to ask how accurate the reconstructed isosurfaces are with respect to the underlying continuous model. A reconstructed isosurface may look impressive when rendered ("photorealism"), but how well does it reflect reality ("physical realism")?;The users of volume visualization packages must be aware of the short-comings of the algorithms used to produce the images so that they may properly interpret, and interact with, …
