The "GEE! It s Simple" package illustrates Gaussian elimination with partial pivoting, which produces a factorization of P*A into the product L*U where P is a permutation matrix, and L and U are lower and upper triangular, respectively. The functions in this package are accurate, but they are far slower than their MATLAB equivalents (x=A\b, [L,U,p]=lu(A), and so on). They are presented here merely to illustrate and educate. "Real" production code should use backslash and lu, not this package.

算術編碼是把一個信源表示為實軸上0和1之間的一個區間,信源集合中的每一個元素都用來縮短這個區間。 算術編碼的過程如下: (1)設定編碼區間的高段為h,編碼區間的長度為g,EndC為編碼字符分配的高段,StartC 為字符分配區間的低端。 (2)根據有限的信源估算出各元素的概率。 (3)杜宇編碼的元素A1,根據(2)估算的概率和區間,計算出該元素編碼后的新的l,和h。

盤覆蓋問題:在一個2k×2k 個方格組成的棋盤中,恰有一個方格與其它方格不同,稱該方格為一特殊方格,且稱該棋盤為一特殊棋盤。在棋盤覆蓋問題中,要用圖示的4種不同形態的L型骨牌覆蓋給定的特殊棋盤上除特殊方格以外的所有方格,且任何2個L型骨牌不得重疊覆蓋。

Problem B:Longest Ordered Subsequence A numeric sequence of ai is ordered if a1 < a2 < ... < aN. Let the subsequence of the given numeric sequence (a1, a2, ..., aN) be any sequence (ai1, ai2, ..., aiK), where 1 <= i1 < i2 < ... < iK <= N. For example, sequence (1, 7, 3, 5, 9, 4, 8) has ordered subsequences, e. g., (1, 7), (3, 4, 8) and many others. All longest ordered subsequences are of length 4, e. g., (1, 3, 5, 8).
