Logical frameworks have enjoyed wide adoption as meta-languages for describing deductive systems. While the techniques for representing object languages in logical frameworks are ...
Relay Ladder Logic (RLL) [4] is a programming language widely used for complex embedded control applications such as manufacturing and amusement park rides. The cost of bugs in RLL...
Open forms of global constraints allow the addition of new variables to an argument during the execution of a constraint program. Such forms are needed for difficult constraint pro...
In this paper we consider the consistency problem of temporal or spatial qualitive constraint networks. A new encoding making it possible to represent and solve this problem in th...
