强化学习——day16 动态规划算法动态规划（dynamic programming）是程序设计算法中非常重要的内容，能够高效解决一些经典问题，例如背包问题和最短路径规划。动态规划的基本思想是将待求解问题分解成若干个子问题，先求解子问题，然后从这些子问题的解得到目标问题的解。动态规划会保存已解决的子问题的答案，在求解目标问题的过程中，需要这些子问题答案时就可以直接利用，避免重复计算。本章介绍如何用动态规划的思想来求解在马尔可夫决策过程中的最优策略阅读详情

编译的时候

DisASM.cpp

NOTE: WINVER has been defined as 0x0500 or greater which enables

Windows NT 5.0 and Windows 98 features. When these headers were released,

Windows NT 5.0 beta 1 and Windows 98 beta 2.1 were the current versions.

For this release when WINVER is defined as 0x0500 or greater, you can only

build beta or test applications.  To build a retail application,

set WINVER to 0x0400 or visit http://www.microsoft.com/msdn/sdk

to see if retail Windows NT 5.0 or Windows 98 headers are available.

See the SDK release notes for more information.

ProesDlg.cpp

搜索了下在windows.h中这样定义的





#if(WINVER >= 0x0500)

#pragma message ("")

#pragma message ("NOTE: WINVER has been defined as 0x0500 or greater which enables")

#pragma message ("Windows NT 5.0 and Windows 98 features. When these headers were released,")

#pragma message ("Windows NT 5.0 beta 1 and Windows 98 beta 2.1 were the current versions.")

#pragma message ("")

#pragma message ("For this release when WINVER is defined as 0x0500 or greater, you can only")

#pragma message ("build beta or test applications.  To build a retail application,")

#pragma message ("set WINVER to 0x0400 or visit http://www.microsoft.com/msdn/sdk")

#pragma message ("to see if retail Windows NT 5.0 or Windows 98 headers are available.")

#pragma message ("")

#pragma message ("See the SDK release notes for more information.")

#pragma message ("")

#endif

我stdafx.h中定义了WINVER 0x0500. 似乎这不是问题的原因.
windows.h明明有#ifndef 这种防止多次编译, 为何build提示中还会出现两遍? 感谢.
