Given a universal constant k, the multiple Stack Travelling Salesman Problem (kSTSP in short) consists in finding a pickup tour T1 and a delivery tour T2 of n items on two distinc...
A key issue in the design of a model-checking tool is the choice of the formal language with which properties are specified. It is now recognized that a good language should exten...
Programmers rely on the correctness of the tools in their programming environments. In the past, semanticists have studied the correctness of compilers and compiler analyses, which...
