Variations of R-Tree Structure for Indexing of Spatial Objects
The data structures suitable for indexing of large spatial objects in databases are considered. Some generalizations of existing tree methods concerned approximation of spatial ob...

From Synchronous to Asynchronous: An Automatic Approach
This paper presents a methodology to derive asynchronous circuits from optimized synchronous circuits by replacing the clock distribution tree by a handshaking network. A case stu...

A Non-Linear Schema Theorem for Genetic Algorithms
We generalize Holland's Schema Theorem to the setting that genes are arranged, not necessarily in a linear sequence, but as the nodes in a connected graph. We have experiment...
