Merge Request - Guideline Checklist

Please check our git workflow. Use the draft feature if the Pull Request is not yet ready to review.

Checks by code author

• Every addressed issue is linked (use the "Closes #ISSUE" keyword below)
• New code adheres to coding guidelines
• No large data files have been added (files should in sum not exceed 100 KB, avoid PDFs, Word docs, etc.)
• Tests are added for new functionality and a local test run was successful (with and without OpenMP)
• Appropriate documentation for new functionality has been added (Doxygen in the code and Markdown files if necessary)
• Proper attention to licenses, especially no new third-party software with conflicting license has been added
• (For ABM development) Checked benchmark results and ran and posted a local test above from before and after development to ensure performance is monitored.

Checks by code reviewer(s)

• Corresponding issue(s) is/are linked and addressed
• Code is clean of development artifacts (no deactivated or commented code lines, no debugging printouts, etc.)
• Appropriate unit tests have been added, CI passes, code coverage and performance is acceptable (did not decrease)
• No large data files added in the whole history of commits(files should in sum not exceed 100 KB, avoid PDFs, Word docs, etc.)
• On merge, add 2-5 lines with the changes (main added features, changed items, or corrected bugs) to the merge-commit-message. This can be taken from the briefly-list-the-changes above (best case) or the separate commit messages (worst case).

Pull Request Overview

This PR removes redundant ABM simulation targets and consolidates simulation setup into the example, updating the example’s initialization logic and renaming the primary ABM example target.

• Deleted standalone ABM simulation executables from cpp/simulations/CMakeLists.txt
• Enhanced abm.cpp to seed infections probabilistically and set mask compliance at person and location levels
• Renamed and updated the ABM example target in cpp/examples/CMakeLists.txt

Reviewed Changes

File	Description
cpp/simulations/CMakeLists.txt	Removed abm_simulation and abm_braunschweig executables
cpp/examples/abm.cpp	Replaced uniform random infection assignment with parameterized probability, added mask compliance logic
cpp/examples/CMakeLists.txt	Renamed abm_history_example to abm_example and updated target

cpp/examples/abm.cpp:150

• Hardcoding TimePoint(0) may misalign the infection start with the configured start_date. Consider using the existing start_date variable to ensure consistency.

model.parameters, mio::abm::TimePoint(0), state));

cpp/examples/abm.cpp:143

• [nitpick] The variable name prng is terse; consider renaming it to personal_rng or similar for clarity about its purpose.

auto prng = mio::abm::PersonalRandomNumberGenerator(person);

cpp/examples/CMakeLists.txt:103

• Ensure that any documentation, scripts, or CI configurations referencing abm_history_example are updated to use the new abm_example target.

[nitpick] Extract the magic number 0.05 into a named constant (e.g., initial_infection_probability) to improve readability and make future adjustments easier.

Suggested change

	auto pct_infected = 0.05;
	auto pct_infected = initial_infection_probability;

[Copilot]

[nitpick] Consider moving these compliance weight values into a named constant or configuration to clarify their meaning and avoid inline literals.
