        In order to use certain construction heuristics, we need to add "planning entity difficulty"
        https://www.optaplanner.org/docs/optaplanner/latest/planner-configuration/planner-configuration.html#planningEntityDifficulty
        and/or "planning value strength"
        https://www.optaplanner.org/docs/optaplanner/latest/planner-configuration/planner-configuration.html#planningValueStrength
        BUT NEITHER OF THESE ARE SUPPORTED YET IN OPTAPY
