Dear all!
The DXC’26 organization committee is proud to announce that there will be a DX competition also in 2026. The contestants can enter their solutions for addressing diagnosis problems in up to three benchmarks. With COMIC there is a new benchmark in the digital domain, but the LUMEN benchmark pauses in 2026 since the team is working hard on generating new data and making a simulator available for the 2027 competition.
The evaluations will be provided before the DX paper submission deadline, so that the contestants can incorporate their results into corresponding papers (please see the submission page for more details such as the page limit). If you do not plan to submit your own paper, please note that it is mandatory to submit a 2 page technical description of your solution to the DXC organization committee to be contained in a summary paper for the competition. Each participant may tackle one, two, or all three benchmarks:
* The LiU-ICE benchmark covers some challenging problems of fault diagnosis of technical systems. The case study is an internal combustion engine, and the goal is to develop a diagnosis system that can diagnose under realistic operating conditions. A structural model of the system and operational data are provided where the data include both nominal and faulty operation. The challenges in the LiU-ICE benchmark include incomplete training data and limited model information.
* SLIDe (Steam Line Intrusion Detection) is devoted to evaluating diagnostic algorithms performing the tasks of detection and isolation of process faults and detection of cybernetic attacks in the third and fourth stages of superheaters of the fluidized bed boiler steam line. It includes challenging scenarios of sensor, actuator and technological component faults and examples of cybernetic attacks. To reflect the industrial nature of the benchmark, the participants will only have access to a qualitative description of the process and several archival datasets representing different operating conditions, but only for fault-free and attack-free states.
* The COMIC benchmark targets the diagnosis of combinatorial circuits known from the ISCAS benchmark suites (see https://ddd.fit.cvut.cz/www/prj/Benchmarks/ for some info on digital design benchmarks). Due to the complexity of diagnosis problems for larger circuits, the contestants are expected to compute all diagnoses of minimal cardinality only. The benchmark contains a set of diagnosis problems that must be computed on the evaluation platform within a given time limit. The algorithms will be rated and ranked based on the fraction of samples that they could solve within the time limit. Please note that there is a prize for the winner of this benchmark that was donated by Johan de Kleer.
* LUMEN (Liquid Upper stage demonstrator Engine) is a modular pump-fed liquid oxygen (LOX) and liquid methane (LNG) rocket engine developed by the Institute of Space Propulsion of the German Aerospace Center (DLR). This benchmark focuses on the fuel turbopump subsystem of the rocket engine and addresses key challenges encountered in safety-critical systems, such as the lack of experimental data from faulty operation. The goal of this benchmark is to utilize information from a simulation model with uncertain parameters and limited experimental data from nominal operation to enable the diagnosis system to perform effectively under realistic operating conditions. Please note that this benchmark pauses for DXC'26. The team is working hard on updated data and a simulator for the competition in 2027.
For more information about the competition as a whole and the individual benchmarks, we refer the interested reader to the DXC'26 website [1] and the DXC’26 repository [2]. There we offer news, detailed information about the challenges and instructions how to enter the competition. Please note that the submission deadline will be April 15th. Please do not hesitate to contact any of the individual benchmark chairs or the competition co-chairs to discuss questions that you might have.

Feedback will be provided around April 29th, so that it can be integrated into your complementing paper submission to the DX conference (deadline May 11th). We would appreciate if you would reach out to us by April 1st about your interest in participating in the competition.
