1. Introduction
This page summarizes the results for the 2023 edition of the Model Checking Contest (MCC’2023). This page is divided in three sections:
- First, we list the qualified tools for the MCC'2023,
- Then, we provide some informations about the experimental conditions of the MCC'2023,
- Then, we present an access to details about results,
- Then, we provide the list of winners of the MCC'2023,
- Finally, we provide an attempt to evaluate tool reliability based on the comparison of the results provided in the contest.
IMPORTANT:all these documents can be reused in scientific material and papers but must respect the Creative Common license CC-BY-NC-SA.
2. List of Qualified Tools in 2023
15 tools where submitted this year. They all successfully went through a qualification process requiring about 1625 runs (each tool had to answer each examination for the first instance of each «known» model).
We introduce two classes of tools :
- Original tools: these are tools prepared for the current year ; it may also be a association of tools or some previously existing tools with additional features. It must be something original.
- Reference tools: these are existing reference tools that have been repackaged for the model checking contest so that they can compete as a identified version ; this may help to measurer the evolution of techniques or to make a comparison between a new version of a given tool and a previous one.
IMPORTANT: all tool developers agreed to provide the original image disk embedding the tool they submitted his year (see links in the table below). You may operate these tools on your own. To do so, you need the second disk image (mounted by the other one) that contains all models for 2023 together with the produced formulas. This image is mounted with the default configuration, as well as in he default disk image provided in the tool submission kit (see here).
IMPORTANT: You also have access to the archive containing all models and the corresponding formulas for 2023 here.
IMPORTANT: Note that Gold2022 is an hybrid artificial tool made with the tools that won categories in 2022. It correspond usually to several virtual machines, so the corresponding archive is a bit larger. For the MCC'2023, Gold 2022 is composed as follows:
- tedd-c for the StateSpace Category
- ITS-Toolsfor the GlobalProperties and UpperBounds categories
- Tapaalfor the Reachability Formulas, CTL Formulas and LTL Formulas categories
The table below presents all participating tools for 2023.

3. Experimental Conditions of the MCC'2023
Each tool was submitted to 21 814 executions in various conditions (1 678 model/instances and 13 examinations per model/instance) for which it could report: DNC (do not compete), CC (cannot compute) or the result of the query. These executions were handled by BenchKit, that was developed in the context of the MCC for massive testing of software. Then, from the raw data provided by BenchKit, some post-analysis scripts consolidated these and computed a ranking.
16 GB of memory were allocated to each virtual machine (both parallel and sequential tools) and a confinement of one hour was considered (execution aborted after one hour). So, a total of 327 210 runs (execution of one examination by the virtual machine) generated 29 GB of raw data (essentially log files and CSV of sampled data).
The table below shows some data about the involved machines and their contribution to the computation of these results. This year, we affected only physical cores to the virtual machines (discarding logical cores obtained from hyper-threading) so the balance between the various machine we used is quite different from he one of past years.

We are pleased to thanks those who helped in the execution of tools:
- Tajo was made available by colleagues at Rostock University,
- Octoginta-2 were made available by colleagues at Université Paris Nanterre and was partially funded by LIP6,
- Tall (we used 13 nodes) and small (we used 23 nodes) are clusters at LIP6 Sorbonne Université & CNRS.

You can download the full archive (7.9 GB compressed and 121 GB uncompressed) of the 327 210 runs processed to compute the results of the MCC'2023. This archive contains execution traces, execution logs and sampling, as well as a large CSV files that summarizes all the executions and gnuplot scripts and data to generate the charts produced in the web site (please have a look on the READ_ME.txt file). You may get separately the two mostly interesting CSV files:
- GlobalSummary.csv that summarizes all results from all runs in the contest (69 MB when expanded),
- raw-result-analysis.csv that contains the same data as the previous one but enriched with scoring information and the expected results (computed as a majority of tools pondered by their confidence rate, 82 MB when expanded).
Note that from the two CSV file, you can identify the unique run identifier that allows you to find the traces and any information in the archive (they are also available on the web site when the too did participated).
5. The Winners for the MCC'2023
This section presents the results for the main examinations that are:
- State Space generation,
- UpperBounds computation,
- GlobalProperties computation (ReachabilityDeadlock , QuasiLiveness, StableMarking, Liveness, OneSafe),
- Reachability Formulas (ReachabilityCardinality, ReachabilityFireability),
- CTL Formulas (CTLCardinality, CTLFireability),
- LTL Formulas (LTLCardinality, LTLFireability),
To avoid a too large disparity between models with numerous instances and those with only one, a normalization was applied so that the score, for an examination and a model, varies between 102 and 221 points. Therefore, providing a correct value may brings a different number of points according to the considered model. A multiplier was applied depending to the model category:
- ×1 for «Known» models,
- ×10 for «Surprise» models.
Let us introduce two «special» tools:
- 2023-gold is an hybrid tool made of the gold-medal for the 2023 edition for each examination. It is a way to evaluate the progress of participants since the last edition of the MCC.
- BVT (Best Virtual Tool) computes the union of all the values computed by all other tools. It is very often the fastest and the tool having the smallest memory footprint, based on what the participating tool performed. It is a way to evaluate the complementarity between tools by comparing it to the gold medal
5.1. Winners in the StateSpace Category
4 tools out of 6 participated in this examination (plus 4 reference). Results based on the scoring shown below is:
- TINA.tedd (called tedd-c because it is the concurrent version) ranked first (16 699 pts),
- GreatSPN ranked second (14 479 pts),
- ITS-Tools ranked third (12 794 pts).
Then, tools rank in the following order: Marcie+Red (11 825 pts), Smart+red (10 853 pts), LTSMin+red (8 806 pts). The the Gold-medal of 2022 collected 16 632 pts. BVT-2023 (Best Virtual Tool) collected 17 354 pts and computed 61.77% of the total number of values in this category.

Remarks about the StateSpace examination
Some detailed results state that marking ins infinite (use of the value «+Inf********»). There are some infinite models in our benchmark but our analysis tools have a constrains in the representation of very large state spaces which is the one of the Long_Long_Float Ada type (maximum value of 1.0E+4932). When watching the execution report of some tools, you can check weather «+Inf********» really means infinite or not.

6. Estimation of the Global Tool Confidence
A confidence analysis enforces the computation of «right results» based on the answers of participating tools. To do so, we considered each value provided in the contest (a value is a partial result such as the result of a formula or a number provided for state space, bound computation, etc.). To do so, we processed as follows:
- For each «line» (all tools for a given examination for a given instance), we selected all «significant values» where at least 3 tools do agree.
- Based on this subset of values, we computed the ratio between the selected values for the tool and the number of good answers hey provide for such values. This ratio gave us a tool confidence rate that is provided in the table below.
- This tool confidence rate rate was then applied to compute the scores presented in the dedicated section.
The table below provides, in first column, the computed confidence rates (that are naturally lower for tools where a bug was detected). Then, the table provides the number of correct results (column 2) out of the number of «significant values» selected for the tool (column 3). The last column shows the number of examinations (and their type) the tool was involved in.
