We consider the satisfiability problem for Boolean combinations of unit two variable per inequality (UTVPI) constraints. A UTVPI constraint is linear constraint containing at mos...
We present the design and the implementation of clp(B): a boolean constraint solver inside the Constraint Logic Programming paradigm. This solver is based on local propagation meth...
Finite domain propagation solving, the basis of constraint programming (CP) solvers, allows building very high-level models of problems, and using highly specific inference encapsu...
The problem of solving boolean combinations of difference constraints is at the core of many important techniques such as planning, scheduling, and model-checking of real-time syst...
Parametric and feature-based CAD models can be considered to represent families of similar objects. In current modelling systems, however, the semantics of such families are uncle...
