We are happy to announce the results of PACE 2022. Congratulations to the winners and all the participants.
The easychair platform to register your solver and later to submit the solver description is now open! See also the submission requirements of PACE 2022.
We have published public instances! Here are public instances for exact track and heuristic track.
More …We are pleased to announce the seventh iteration of PACE, the Parameterized Algorithms and Computational Experiments Challenge! The challenge for this year is Directed Feedback Vertex Set. Find the details here.
We are happy to announce the results of PACE 2021. Congratulations to the winners and all the participants.
We have published public instances! Here are public instances for exact track and kernelization track and heuristic track.
More …We are pleased to announce the sixth iteration of PACE, the Parameterized Algorithms and Computational Experiments Challenge! The challenge for this year is Cluster Editing. Find the details here.
We created a repository which contains all our (public and private) instances. Enjoy! Each instance file has comment lines with instance type (e.g. biology, social networks), origin and description. We hope that the repo will be useful for future PACE organizers and for researchers working in algorithm engineering.
We are happy to announce the results of PACE 2020. Congratulations to the winners and all the participants. You are great!
More …We decided that:
We are happy to announce that you can now submit your solutions to optil.io. Let us recall that the final deadline for submission is June, 1. Until the submission deadline, you will be able to test your solution on public instances and see unofficial rankings. Please note that the ranking published at optil.io is only auxiliary. In particular:
More …Felix Reidl designed a poster for us! See / download the poster below.
More …Detailed rules of the two tracks of PACE 2020 and public instances are now online, enjoy! See the PACE 2020 challenge description and general information.
We are happy to announce the fifth iteration of PACE, the Parameterized Algorithms and Computational Experiments Challenge. The goal of PACE is to investigate the applicability of algorithmic ideas studied and developed in the subfields of multivariate, fine-grained, parameterized, or fixed-parameter tractable algorithms.
More …We published the private and public instances for both tracks on Zenodo. For details we refer to: 1) Instances from the Vertex Cover Track 2) Instances from both Hypertree Decomposition Tracks
We published preliminary results of the PACE2019 challenge. The final results and winners will be announced during the award ceremony at IPEC2019 in Munich.
Due to problems with the submission system easychair, we extend the deadline until Monday June 3rd, 2019 (AOE). We’ve been informed on May 30th that easychair is experiencing network problems which however should have already beenresolved on May 31st (see below). Nonetheless, due to several requests still reporting problems, we decided to extend the deadline further.
More …Jan from optil.io informed us that their system sometimes gets stuck when a submission is killed due to reaching the time limit.
More …The issue should be resolved.
More …We are currently experiencing some issues with the optil system. The problem was first reported yesterday. According to optil, they ran a system update. We are in contact with the optil team. Unfortunately, there is a public holiday on May 1st and May 3rd in Poland, so we might get answers not before Monday.
More …We are happy to announce the fourth iteration of PACE, the Parameterized Algorithms and Computational Experiments Challenge. The goal of PACE is to investigate the applicability of algorithmic ideas studied and developed in the subfields of multivariate, fine-grained, parameterized, or fixed-parameter tractable algorithms. This year, the challenge consists of two separate tracks.
More …The award ceremony took place in Helsinki. The slides are available and show the results.
More …We are happy to announce that PACE 2018 will cooperate again with OPTIL.io to handle the submission process and the evaluation of the submissions. OPTIL.io is a website for organizing programming challenges on optimization problems, created and maintained by the Institute of Computing Science of Poznan University of Technology.
More …The PACE 2018 challenge has started! This year there is only one problem, Steiner Tree, and three tracks: two for exact algorithms and one for heuristics. To register your team now and find out all the details of the challenge, visit the challenge page.
Due to numerous requests, we decided to allow submissions for Track A and Track B until May 25. Thanks to the cooperation with OPTIL.io, we can still send out the notification on June 1.
More …March 1 has passed which means that submission is possible from now until May 1 for both tracks of PACE 2017.
More …We are happy to announce the second iteration of PACE, the Parameterized Algorithms and Computational Experiments Challenge. The goal of PACE is to investigate the applicability of algorithmic ideas studied and developed in the subfields of multivariate, fine-grained, parameterized, or fixed-parameter tractable algorithms. The challenge consists of two separate tracks.
More …The winners of the 1st PACE competition were presented at ALGO 2016 in Aarhus. For those that couldn’t make it to Aarhus: here are the results. We would like to thank all participants for making this 1st edition of PACE an enjoyable and successful one.
More …Thanks to the generous support of the NWO Gravitation project NETWORKS, we can announce the following awards for the first PACE challenge.
