Abstract

Multi-layer graphs consist of several graphs (layers) over the same vertex set. They are motivated by real-world problems where enti-ties (vertices) are assoc iated via multiple types of relationships (edges in different layers). We chart the border of computational (in)tractability for the class of subgraph detection problems on multi-layer graphs, including fundamental problems such as m aximum matching, finding certain clique relaxations (motivated by community detection), or path problems. Mostly encountering hardness results, sometimes even for two or three layers, we can also spot some islands of tractability.
