In such cases, one has often to formally verify that a constraint system is unsatis able, as it is required to prove that no reachable states can violate the property to be ensured. Unfortunately, proving that a constraint system is unsatis able is much more complex for a CP-solver than checking a possible solution.}, year = {2014}, journal = {Selected talk at the {\textquoteright}Verification meets CP{\textquoteright} 2014 workshop, Lyon, France}, }
