我看到一个博客，用于缩放VRPTW的1000多个位置使用附近的选择。我试着实现它，下面是我编写的xml：

<unionMoveSelector>
            <changeMoveSelector>
                <entitySelector id="entitySelector1">
                    <entityClass>vehiclerouting.domain.Customer</entityClass>
                </entitySelector>
                <valueSelector variableName="previousStandstill">
                    <nearbySelection>
                        <originEntitySelector mimicSelectorRef="entitySelector1"/>
                        <nearbyDistanceMeterClass>vehiclerouting.domain.solver.nearby.CustomerNearbyDistanceMeter</nearbyDistanceMeterClass>
                        `<nearbySelectionDistributionType>PARABOLIC_DISTRIBUTION</nearbySelectionDistributionType>
                    </nearbySelection>
                </valueSelector>
            </changeMoveSelector>
            <swapMoveSelector>
                <entitySelector id="entitySelector2">
                    <entityClass>vehiclerouting.domain.Customer</entityClass>
                </entitySelector>
               <secondaryEntitySelector>
                    <entityClass>vehiclerouting.domain.Customer</entityClass>
                    <nearbySelection>
                        <originEntitySelector mimicSelectorRef="entitySelector2"/>
                        <nearbyDistanceMeterClass>vehiclerouting.domain.solver.nearby.CustomerNearbyDistanceMeter</nearbyDistanceMeterClass>
                        <nearbySelectionDistributionType>PARABOLIC_DISTRIBUTION</nearbySelectionDistributionType>
                    </nearbySelection>
                </secondaryEntitySelector>
            </swapMoveSelector>
        </unionMoveSelector>

下面是我获得的异常(与154个客户一起运行时)：

我想，我可能在xml配置中做错了一些事情。谢谢你的帮助。

这是不可能的，因为在7.7.0中东方就有至少一次检查的sizeMaximum了。最后和晚些时候(还有很多版本也会提前)。
