Mapping Data in Peer-to-Peer Systems: Semantics and Algorithmic Issues
We consider the problem of mapping data in peer-topeer data-sharing systems. Such systems often rely on the use of mapping tables listing pairs of corresponding values to search f...

Data Mining Using Cultural Algorithms and Regional Schemata
In the paper we demonstrate how evolutionary search for functional optima can be used as a vehicle for data mining. That is, in the process of searching for optima in a multi-dime...
