✦ Synopsis


The graph coloring problem is a classic one in combinatorial optimization with a diverse set of significant applications in science and engineering. In this paper, we study several versions of this problem generalized to hypergraphs and develop solutions based on the neural network approach. We experimentally evaluate the proposed algorithms, as well as some conventional ones, on certain types of random hypergraphs. We also evaluate our algorithms on specialized hypergraphs arising in implementations of parallel data structures. The neural network algorithms turn out to be competitive with the conventional ones we study. Finally, we construct a family of hypergraphs that is hard for a greedy strong coloring algorithm, whereas our neural network solutions perform quite well.

## Abstract This article discusses problems in the context of multicommodity network design where additional constraints (such as capacity), rather than being imposed in a strict manner, are allowed to be violated at the expense of additional penalty costs. Such penalized cost structures allow thes
