    Hi Vincent,

    This is not surprising. Nowadays, most solvers suffer from high variability: Small changes in the model can lead to a different solution path in the algorithms, which may lead to very different runtimes. By chance, e.g., one of the built-in heuristics finds a solution earlier, etc. See this article for some discussion on this topic. Changing the random seed value (parameter Seed) for the same model might also lead to different runtimes.

    Best regards,
    Mario
