In this paper we test whether a correlation exists between the optimal mutation rate and problem difficulty. We find that the range of optimal mutation rates is inversely proporti...
The performance of a database system depends strongly on the layout of database objects, such as indexes or tables, onto the underlying storage devices. A good layout will both ba...
Abstract. An important application of unique object references is safe and efficient message passing in concurrent object-oriented programming. However, to prevent the ill effects...
We study revision programming, a logic-based mechanism for enforcing constraints on databases. The central concept of this approach is that of a justi ed revision based on a revisi...

A future is a well-known programming construct used to introduce concurrency to sequential programs. Computations annotated as futures are executed asynchronously and run concurren...
