这是学校ACM程序设计大赛的题目,拿出来大家算是当练习

0 / 1背包问题是一个N P-复杂问题，为了解决该问题，，将用回溯算法解决该问题。既然想选择一个对象的子集，将它们装入背包，以便获得的收益最大，则解空间应组织成子集树的形状（如图1 6 - 2所示）。该回溯算法与4 . 2节的装载问题很类似。首先形成一个递归算法，去找到可获得的最大收益。然后，对该算法加以改进，形成代码。改进后的代码可找到获得最大收益时包含在背包中的对象的集合。-0/1 knapsack problem is a P-complex issues, in order to solve the problem, and will be used backtracking algorithm to solve the problem. As to the choice of a subset of object, they will load a backpack, in order to obtain the greatest profits, the solution should be organized into space subset of the shape of the tree (Figure 1 6-2 below). The backtracking algorithms and 4. Two loading problem is very similar. Forming a recursive algorithm to get the maximum benefit available. Then, this algorithm is modified to form code. Improved code can be found at the maximum benefits included in the backpack of a collection of objects.

资源描述      有资源我愿共享，希望各位通辽互相帮助，互相学习，互相进步，CSDN！蚁群算法实现！蚁群算法的应用有很多，TSP问题，NP问题，可以与遗传算法结合起来，群体智慧！如有不足请多指教！蚁群算法运用于图像复原，碎纸拼接，修复破损文物等等。

The cart with an inverted pendulum, shown below, is "bumped" with an impulse force, F. Determine the dynamic equations of motion for the system, and lin earize about the pendulum s angle, theta = Pi (in other words, assume that p endulum does not move more than a few degrees away from the vertical, chosen to be at an angle of Pi). Find a controller to satisfy all of the design re quirements given below. -The cart with an inverted pendulum, shown below, is "bumped" with an impulse force, F.

资源描述语法分析是编译程序的重要组成部分，LR分析法是一种自下而上的语法分析方法，其适用范围大，在编译程序中大都采用此法进行语法分析，单反分析则是LR中一种较简单有效的分析法；语法分析作为编译过程中一个不可缺少的步骤，对其进行研究有着非常重要的意义。
