摘要:

许多组合优化问题可以用约束满足问题的语言来表述。我们引入了一个图神经网络架构来解决这样的优化问题。该架构是通用的,它适用于所有二进制约束满足问题。训练是无监督的,在相对较小的实例上进行训练就足够了;产生的网络在大得多的实例(至少大10倍)上表现良好。我们实验评估我们的方法,各种问题,包括最大割和最大独立集。尽管是通用的,我们表明,我们的方法匹配或超越最贪婪和半定编程为基础的算法,有时甚至优于国家的最先进的具体问题的算法。

英文摘要:

Many combinatorial optimization problems can be phrased in the language of constraint satisfaction problems. We introduce a graph neural network architecture for solving such optimization problems. The architecture is generic; it works for all binary constraint satisfaction problems. Training is unsupervised, and it is sufficient to train on relatively small instances; the resulting networks perform well on much larger instances (at least 10-times larger). We experimentally evaluate our approach for a variety of problems, including Maximum Cut and Maximum Independent Set. Despite being generic, we show that our approach matches or surpasses most greedy and semi-definite programming based algorithms and sometimes even outperforms state-of-the-art heuristics for the specific problems.
