так что в основном моя проблема в том, что OptaPlanner выдает это:
java.lang.IllegalStateException: The entity (...) has a variable (previousEntry) with value (...) which has a sourceVariableName variable (nextEntry) with a value (...) which is not null.
Verify the consistency of your input problem for that sourceVariableName variable.

Я создаю ход, используя это:
<cartesianProductMoveSelector>
<ignoreEmptyChildIterators>true</ignoreEmptyChildIterators>
<changeMoveSelector/>
<swapMoveSelector/>
</cartesianProductMoveSelector>
Я пытаюсь оптимизировать цепочку, поэтому у меня есть теневая переменная (nextEntry) для моей плановой переменной previousEntry. Все работает, если я использую unionMoveSelector, но теперь я хочу попытаться объединить свои движения, чтобы OptaPlanner мог выбраться из локального оптимума. У меня только 1 глиссирующая переменная.
РЕДАКТИРОВАТЬ: только что обновлен до 7.19.0.Final проблема все еще существует ...
EDIT2: только что протестирован с FULL_ASSERT и получил тот же результат, без cartesianProductMoveSelector Я получаю результат:
Solving ended: time spent (371190), best score (0hard/-31648770soft), score calculation speed (81/sec), phase total (3), environment mode (FULL_ASSERT).
Если я добавлю cartesianProductMoveSelector, я получу точно такое же исключение
EDIT3: я только что проверил это на vrp-примере optaplanner (7.17.0.Final) и получил точно такое же исключение:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: Solving failed.
