The multi-task phase of the campaign included the optimisation of the EOL and the ionic conductivity in parallel. The MD tenant and the ASAB tenant started their contribution of results to the database approximately 5 hours apart, which is significantly shorter than 8 days in the single-task phase. Both optimiser instances, OCond and OEOL, were running at the same time, concurrently posting requests for their respective task. The multi-task phase was started on the 6 th of November 2023 and lasted until the last result was posted on the 14 th of December 2023. During this time, a total of 274 result entries were posted to FINALES. In the multi-task phase, 7 quantities and 9 methods were registered with FINALES. Out of the 274 results, 173 are valid.
