Abstract
We present a simple heuristic for the Cluster Editing Problem as presented in the Parameterized Algorithms and Computational Experiments (PACE) 2021. Our method makes use of a simple Threshold Accepting strategy and employs single neighborhood moves only. Despite its simplicity, the results of the method are encouraging. However, and this has to be expected, the approach cannot ultimately win in a competitive setting such as PACE 2021. Nevertheless, some interesting insights can be derived from such a simple method, as this gives an idea of how good results can be by a comparable basic approach with a reasonable implementation effort.
