動態規劃的方程大家都知道，就是 f[i,j]=min{f[i-1,j-1],f[i-1,j],f[i,j-1],f[i,j+1]}+a[i,j] 但是很多人會懷疑這道題的后效性而放棄動規做法。 本來我還想做Dijkstra，后來變了沒二十行pascal就告訴我數組越界了……（dist:array[1..1000*1001 div 2]...） 無奈之余看了xj_kidb1的題解，剛開始還覺得有問題，后來豁然開朗…… 反復動規。上山容易下山難，我們可以從上往下走，最后輸出f[n][1]。 xj_kidb1的一個技巧很重要，每次令f[i][0]=f[i][i],f[i][i+1]=f[i][1]（xj_kidb1的題解還寫錯了）

//Euler 函數前n項和 /* phi(n) 為n的Euler原函數 if( (n/p) ％ i == 0 ) phi(n)=phi(n/p)*i else phi(n)=phi(n/p)*(i-1) 對于約數：divnum 如果i|pr[j] 那么 divnum[i*pr[j]]=divsum[i]/(e[i]+1)*(e[i]+2) //最小素因子次數加1 否則 divnum[i*pr[j]]=divnum[i]*divnum[pr[j]] //滿足積性函數條件 對于素因子的冪次 e[i] 如果i|pr[j] e[i*pr[j]]=e[i]+1 //最小素因子次數加1 否則 e[i*pr[j]]=1 //pr[j]為1次 對于本題： 1. 篩素數的時候首先會判斷i是否是素數。 根據定義，當 x 是素數時 phi[x] = x-1 因此這里我們可以直接寫上 phi[i] = i-1 2. 接著我們會看prime[j]是否是i的約數 如果是，那么根據上述推導，我們有：phi[ i * prime[j] ] = phi[i] * prime[j] 否則 phi[ i * prime[j] ] = phi[i] * (prime[j]-1) (其實這里prime[j]-1就是phi[prime[j]]，利用了歐拉函數的積性) 經過以上改良，在篩完素數后，我們就計算出了phi[]的所有值。 我們求出phi[]的前綴和 */

Instead of finding the longest common subsequence, let us try to determine the length of the LCS. Then tracking back to find the LCS. Consider a1a2…am and b1b2…bn. Case 1: am=bn. The LCS must contain am, we have to find the LCS of a1a2…am-1 and b1b2…bn-1. Case 2: am≠bn. Wehave to find the LCS of a1a2…am-1 and b1b2…bn, and a1a2…am and b b b b1b2…bn-1 Let A = a1 a2 … am and B = b1 b2 … bn Let Li j denote the length of the longest i,g g common subsequence of a1 a2 … ai and b1 b2 … bj. Li,j = Li-1,j-1 + 1 if ai=bj max{ L L } a≠b i-1,j, i,j-1 if ai≠j L0,0 = L0,j = Li,0 = 0 for 1≤i≤m, 1≤j≤n.

經典動態壓縮DP，狀態是f[i][j]，表示第i行，以3進制j為狀態。j的位代表一個格子，只能是：0表示第i行和第i - 1行都沒有炮兵，1表示第i行沒有炮兵而第i-1行有炮兵，2表示第i行有炮兵

嚴格按照BP網絡計算公式來設計的一個matlab程序,對BP網絡進行了優化設計 優化1：設計了yyy，即在o(k)計算公式時，當網絡進入平坦區時(<0.0001)學習率加大，出來后學習率又還原 優化2：v(i,j)=v(i,j)+deltv(i,j)+a*dv(i,j)
