Abstract. This paper proposes to promote constraints to first-class status. In contrast to constraint propagation, which performs inference on values of variables, first-class co...
Abstract. Blum and Blum (1975) showed that a class B of suitable recursive approximations to the halting problem is reliably EX-learnable. These investigations are carried on by sh...
In distributed object systems, remote method inattempts to abstract communication between di erent machines to the level of object method invocation. Link failure in such systems ...
Abstract. In this article we introduce (combinatorial) multi{color discrepancy and generalize some classical results from 2{color discrepancy theory to ccolors. We give a recursive...
The hypermedia field has long realized the need for firstructural abstractions. However, we have failed to generalize the concept of ubiquitous structure management to problem dom...
