经典的背包问题用分支限界法实现的JAVA代码-Classical knapsack problem using branch and bound method of the JAVA code

比较了求解0-1背包问题常用的几种算法，并用回溯法和分支限界法进行了Java编程实现，给出了文档及源码。-0-1 knapsack problem compared several commonly used algorithms, and use backtracking and branch and bound method of the Java programming, given the documentation and source code.

用java实现的01背包问题的有分支限界的回溯算法，注释非常详细，是我作业的一部分。伪代码可以参考《计算机算法与数据结构》这本书-Using java to achieve 01 knapsack problem branch-and-bound backtracking algorithm and very detailed notes, is part of my job. The pseudo-code can refer to this book of computer algorith
