原题链接:http://acm.csu.edu.cn/OnlineJudge/problem.php?id=1424 逐渐找到做这种题的感觉了. 二分法.g[i][j]存储坐标(i, j)的值,s[i][j]存储的值为左上角为起始点(1,1),右下角为(i, j)的矩形区域内所有值的和,那么: s[i][j] = g[i][j] + s[i-1][j] + s[i][j-1] - s[i-1][j-1] 扫描整个矩形,遇到为“1”的点就将其作为起点,开始二分边长,利用数组s在O(1)的时间复杂度…

对抗网络是14年Goodfellow Ian在论文Generative Adversarial Nets中提出来的. 原理方面,对抗网络可以简单归纳为一个生成器(generator)和一个判断器(discriminator)之间博弈的过程.整个网络训练的过程中, 两个模块的分工 判断网络,直观来看就是一个简单的神经网络结构,输入就是一副图像,输出就是一个概率值,用于判断真假使用(概率值大于0.5那就是真,小于0.5那就是假) 生成网络,同样也可以看成是一个神经网络模型,输入是一组随机数Z,输出是…
