Round F. Group Projects(DP)
题目链接:点击打开链接题意:给n个人,让我们分成若干组,每组的值是最大值减去最小值,求所有组的和。思路:显然,需要用DP的思想,但是该题DP设计的非常巧妙,而且状态转移的情况容易考虑不全。我们用d[i][j][v]表示考虑了前i个数了,有j个组是开放的(所谓开放指的是只有最小值,还没有最大值,还可以进人),当前值之和为v的方案数。我们先排序,这样,对于开放的组,每次的累加量就都是j*(a[i]-a

题目链接:点击打开链接题意:给你n个数,要求选若干个数,使得这些数的平均数减去中位数尽量大。思路:由于该题没有顺序问题,排好序之后我们可以枚举中位数,可以证明,奇数个数一定比偶数优,然后三分中位数左右区间长度x(数的个数),在中位数的右边选最大的x个数,在左边也选最大的x个,这样,随着区间长度的增加,平均数将先增大后减小,或者一直减小,或者一直增大。为什么呢?假设第一次的区间长度是1,那么我们选择

高斯消元法(Gauss
Elimination
) 分析 & 题解 & 模板——czyuan原创
高斯消元法,是线性代数中的一个算法,可用来求解线性方程组,并可以求出矩阵的秩,以及求出可逆方阵的逆矩阵。高斯消元法的原理是:若用初等行变换将增广矩阵 化为 ,则AX = B与CX = D是同解方程组。所以我们可以用初等行变换把增广矩阵转换为行阶梯阵,然后回代求出方程的解。 以上是线性代数课的回顾,下面来说说高斯消元法在编程中的应用。 首先,先介绍程序中高斯消元法的步骤:(我们设方程组中方程的个
