In a graph-theoretic version for a graph G,it is to find a set F of added edges such that the graph G+F is chordal and |F| is minimized.Here the minimum value |F| is called the finll-in number of G,denoted as f.

起源于稀疏矩阵计算和其它应用领域的图G的最小填充问题是在图G中寻求一个内含边数最小的边集F使得G+F是弦图。

The fill-in minimization problem comes from the elimination process of sparse matrix computation. In a graph-theoretic version for a graph G, it is to find a set F of added edges such that the graph G+F is chordal and |F| is minimized.

起源于稀疏矩阵计算和其它应用领域的图G的最小填充问题是在图G中寻求一个内含边数最小的边集F使得G+F是弦图。

A central issue in PCA is choosing the number of principal components to retain. However, most studies assume a known dimension or determine it heuristically, though there have a number of model selection criteria.

确定观测数据集的本征维数是主分量分析的一个核心问题，然而目前的研究仍然多采用经验方式来进行估计，所得到的结果往往不是最优的。
