Motivated by description logics, we investigate what happens to the complexity of modal satisfiability problems if we only allow formulas built from literals, , 3, and 2. Previous...
The range searching problem is a fundamental problem in computational geometry, with numerous important applications. Most research has focused on solving this problem exactly, bu...
Salsa is an invariant checker for speci cations in SAL the SCR Abstract Language. To establish a formula as an invariant without any user guidance Salsa carries out an induction pr...
The SCOOPP (Scalable Object Oriented Parallel Programming) system is an hybrid compile and run-time system. SCOOPP dynamically scales OO applications on a wide range of target plat...
: Retrenchment is introduced as a liberalisation of refinement intended to address some of the shortcomings of refinement as sole means of progressing from simple abstract models t...
