Optaplanner列表计划变量 [英] Optaplanner List Planning variable

问题描述

下载了OptaPlanner示例，并对它们进行了测试.在提供的会议计划示例中，在解决的解决方案中返回单个计划变量.例如，对于会议安排，将返回一个会议室.如果位置不同(假设为远程会议室启用了VC)，我打算为一个会议安排分配多个会议室.当前会议计划示例未显示此信息.我需要将计划变量室更改为列表吗?

Downloaded OptaPlanner examples, testing them. In the Meeting Scheduling example provided, a single planning variable is returned in the solved solution. for example, for a meeting scheduling, one Room is returned. I am planning to allocate multiple rooms for a single meeting schedule if the locations are different (assuming VC enabled for remote rooms). Current Meeting Scheduling example does not show this. Do I need to change the planning variable room to a List?

推荐答案

计划变量可以采用由ValueRangeProviderRefs指定的一系列值.这总是 一个Collections对象.

Planning variables can take on a range of values, as specified by ValueRangeProviderRefs. This is always a Collections object.

检查@PlanningSolution类.那里应该有一个注释:@ValueRangeProvider(id="...")，它返回仅由一个单间组成的List.修改它以返回房间列表.您可能还需要调整计分机制，以考虑多个房间.

Check the @PlanningSolution class. There should be a annotation there: @ValueRangeProvider(id="..."), that returns a List comprised of just 1 single room. Modify this to return a list of rooms. You'll probably also need to adjust the scoring mechanism to account for multiple rooms.
