群的背包问题

Knapsack Problems in Groups

Alexei Myasnikov, Andrey Nikolaev, Alexander Ushakov

摘要:

我们将经典的背包问题和子集和问题推广到任意群,并研究了这些新问题的计算复杂性。我们表明,这些问题,以及有界的submonoid成员资格问题,是P-时间判定的双曲群,并给出各种例子,其中的子集和问题是NP-完全的群。

英文摘要:

We generalize the classical knapsack and subset sum problems to arbitrary groups and study the computational complexity of these new problems. We show that these problems, as well as the bounded submonoid membership problem, are P-time decidable in hyperbolic groups and give various examples of finitely presented groups where the subset sum problem is NP-complete.
