Abstract This paper describes a general framework for automatic termination analysis of logic programs, where we understand by termination" the niteness of the LD-tree constru...
Linearly bounded Turing machines have been mainly studied as acceptors for context-sensitive languages. We define a natural family of canonical infinite automata representing their...
We define a new model called O-PRS that extends the Process Rewrite Systems formalism with a new associative operator, “ ”, that allows to model parallel composition while ke...
In most models of computation, a device performs some type of process, and only some final output is regarded as the result. In adding an observer to such a device, one can obtain ...
The safety of infinite state systems can be checked by a backward reachability procedure. For certain classes of systems, it is possible to prove the termination of the procedure ...
