自动机群的背包问题

Knapsack problem for automaton groups

Thibault Godin

摘要:

背包问题是一个经典的优化问题,最近已扩展到组的设置。它的研究表明是有趣的,因为它提供了许多不同的行为,这取决于所考虑的群体类别。在本文中,我们处理的群体所产生的Mealy自动机,一类是经常被用来研究组理论programmures-and证明背包问题是不可判定的这一类。在第二次,我们构造一个图,如果有限,提供了一个背包问题的解决方案。我们推断,背包问题是可判定的所谓的有界自动机组,一类的顺序和共轭问题已经知道是可判定的。

英文摘要:

The knapsack problem is a classic optimisation problem that has been recently extended in the setting of groups. Its study reveals to be interesting since it provides many different behaviours, depending on the considered class of groups. In this paper we deal with groups generated by Mealy automata-a class that is often used to study group-theoretical conjectures-and prove that the knapsack problem is undecidable for this class. In a second time, we construct a graph that, if finite, provides a solution to the knapsack problem. We deduce that the knapsack problem is decidable for the so-called bounded automaton groups, a class where the order and conjugacy problems are already known to be decidable.
