1·The interval polynomials, the polytope of polynomials and the inter-val matrices are introduced in this paper.
本文对区间多项式、多项式多面体、区间矩阵作了介绍；
2·The general fractional matching polytope is half-integral, so there exists an optimal solution with edge labels in {0, 1/2, 1}.
一般的分数匹配多面体是半整数，所以存在与{ 0边标签的最佳解决方案，1 / 2，1 }。
