The importance of direct methods discussed in the previous work is unquestionable, since in some practical engineering problems, information about the values of the objective function is the only reliable information, which may have a researcher.

看论坛上有个要钱的关于数学运算表达式的东西，之前写过一个关于数学表达式的单元，现免费发给大家了，当然因为只是临时用才写的，有些粗糙，请原谅。-Have a look forum money on things mathematical expressions, written before the mathematical expression on the cell, is distributed free to the U.S., of course, because it is only a temporary use only written, some rough, please forgive me.

01背包是在M件物品取出若干件放在空间为W的背包里，每件物品的体积为W1，W2……Wn，与之相对应的价值为P1,P2……Pn。考虑用动态规划的方法来解决，这里的：阶段是：在前N件物品中，选取若干件物品放入背包中； 状态是：在前N件物品中，选取若干件物品放入所剩空间为W的背包中的所能获得的最大价值；决策是：第N件物品放或者不放； 由此可以写出动态转移方程：我们用f[i,j]表示在前 i 件物品中选择若干件放在所剩空间为 j 的背包里所能获得的最大价值f[i, j] = max( f[i-1, j-Wi] + Pi (j >= Wi), f[i-1, j] )
