我该如何配置延迟接受算法？

Question

我在修改应用算法时遇到一些问题：首先，看来我无法更改延迟接受算法的配置。这是我的本地搜索配置，当我既未指定acceptor也未指定forager时，它会很好地工作：

<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>

我得到此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，我将延迟接受大小设置为唯一参数（因此将延迟接受作为接受者），而不是将其写下来作为本地搜索类型。

<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>
