[DMANET] PACE 2022 Second Call for Participation

PACE 2022 Call for Participation

We are happy to announce the seventh iteration of PACE, the
Parameterized Algorithms and Computational Experiments Challenge. The
goals of PACE as well as official reports for past challenges can be
found on our website: https://pacechallenge.org/.

This year, the challenge is on Directed Feedback Vertex Set:
* Input: A directed graph
* Output: Find a minimum subset X of V such that, when all vertices of X
and their adjacent edges are deleted from G, the remainder is acyclic.

** Tracks
------------------------------------------------------------
We will have one track for Exact algorithms and another for Heuristic
algorithms.

**Exact:**
Your task is to find an optimal solution of each Directed Feedback
Vertex Set instance within the time limit of 30 minutes.
You will be ranked by the number of solved instances.

**Heuristic:**
Your task is to find the best solution of each Directed Feedback Vertex
Set instance within the time limit of 10 minutes.
You will be ranked by the quality of the solution.
