Graph Neural Networks for Maximum Constraint Satisfaction

Graph Neural Networks for Maximum Constraint Satisfaction

Blog Article

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 Baby Care 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 VITAMIN D CONC.DROPS outperforms state-of-the-art heuristics for the specific problems.
