如何配置延迟接受算法

Question

在修改应用的算法时，我遇到了一些问题：首先，我似乎无法更改延迟接受算法的配置。这是我的本地搜索配置，当我既没有指定接受者也没有指定觅食者时，它可以很好地工作：

<localSearch>
<localSearchType>LATE_ACCEPTANCE</localSearchType>
<acceptor>
<lateAcceptanceSize>5000</lateAcceptanceSize>
<entityTabuRatio>0.1</entityTabuRatio>
<!--valueTabuSize>10000</valueTabuSize-->
</acceptor>
<forager>
<acceptedCountLimit>1</acceptedCountLimit>
</forager>
<termination>
<minutesSpentLimit>10</minutesSpentLimit>
<bestScoreLimit>[0/11496/11496]hard/[0]soft</bestScoreLimit>
</termination>
</localSearch>

我得到这个错误消息作为输出的一部分

java.lang.IllegalArgumentException: The localSearchType (... 
java.lang.IllegalArgumentException: The localSearchType (LATE_ACCEPTANCE) must not be configured if the acceptorConfig (AcceptorConfig()) is explicitly configured.

Answer 1

最后，我被告知同时配置LATE_ACCEPTANCE和lateAcceptanceSize是不兼容的。因此，我将late acceptance size设置为唯一的参数(因此，late acception作为受体(，而不是将其写为本地搜索类型。

<localSearch>
<acceptor>
<lateAcceptanceSize>5000</lateAcceptanceSize>
<entityTabuRatio>0.1</entityTabuRatio>
<!--valueTabuSize>10000</valueTabuSize-->
</acceptor>
<forager>
<acceptedCountLimit>1</acceptedCountLimit>
</forager>
<termination>
<minutesSpentLimit>10</minutesSpentLimit>
<bestScoreLimit>[0/11496/11496]hard/[0]soft</bestScoreLimit>
</termination>
</localSearch>
