[Mathimatics-Numerical algorithms] 透视仪

Description: 一个acm算法题目问题描述：有一个黑盒子，可视为一个15×10的二维矩阵，里面有一些空隙，在二维矩阵中用0表示空隙，用1表示被占有。现有一个仪器，可以从4个方向对盒子进行分行透视：从左到右，从左下到右上，从下到上，从右下到左上。透视可得到该二维矩阵的该行1的个数。要求，还原此矩阵。输入：4行，每一行分别代表从左到右，从左下到右上，从下到上，从右下到左上透视所得的数据输出：该矩阵使用的方法是回溯法，具体见程序-a acm algorithm topic Problem description : a black box, as a 15 x 10 two-dimensional matrix, there are some gaps in two-dimensional matrix using 0 indicates the gap, with a show that occupies. An existing equipment, from the direction of four branches box for perspective : from left to right, from the lower left to upper right, from bottom to top, from the lower right to upper left. Perspective availability of the two-dimensional matrix of the line a number. Demand reduction of this matrix. Input : 4 firms on behalf of every line from left to right, from the lower left to upper right, from bottom to top, from the upper left to lower right perspective on data obtained from the output : the matrix method is the use of backtracking, see the specific procedures

Description: 八皇后VC图形演示，算法思想：回溯法，先在第1行放上一个皇后，然后在第2行合适的位置放上一个皇后，依次类推，如果8行都放满了，说明找到了一个解，如果第好第i行的皇后后，第i+1行找不到合适的位置，这时就回到第i行，把第i行的皇后放到下一个位置，继续尝试下一行。如此反复，知道找到所有的解。注意，这种算法找的解可能有等价的，某些解可由别的解经过旋转棋盘得到。-visual demostration in vc of eight queens problem. algorithm: backtracking. First, put a queen on first line then find a suitable position on 2nd line for next queen, and so on. When all eight lines have queens, it means we have find a solution. If we put the i-th queen, but can find a suitable position on the (i+1)th line, then back to the ith line and move the queen on the ith line to next suitable position and move on to the next line. Repeat this until we have found all the solutions. Note:By this mean, some solutions maybe equivalent to others, some can be acquired by the rotation of other solutions.

[Mathimatics-Numerical algorithms] 上大_net-0-1背包问题(回朔法)

Description: 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.
