Sur le Monoide Syntactique de L Lorsque L est un Langage Fini

We prove that for every finite monoid M , there exists a finite language L such that M divides the syntactic monoid of L∗. Moreover, one can choose for L a full finite prefix code. The same result for finite group has already been proved by Schützenberger. This result is crucial in the proof of the J.-F. Perrot’s theorem that the only variety closed under star operation is the variety of all ra...

Planifier lorsque le but change. Une approche inspirée de la recherche de cible mouvante

In this paper, we propose a novel planner, called Moving Goal Planner (MGP) in order to adapt plans when the goal changes over time. This planner draws inspiration from Moving Target Search (MTS) algorithms. In order to limit the number of search iterations and to improve its efficiency, MGP delays as much as possible starting new searches when the goal changes. To this purpose, MGP uses two st...

Column: File Cabinet Forensics

Reverse Engineering is the traditional bread-and-butter of digital forensics research. Companies like Microsoft and Apple deliver computational artifacts (operating systems, applications and phones) to the commercial market. These artifacts are bought and used by billions. Some have evil intent, and (if society is lucky), the computers end up in the hands of law enforcement. Unfortunately the o...
