1、Sets,2,2020/9/4,College of Computer Science & Technology, BUPT,Introduction to Set Theory,A set is a new type of structure, representing an unordered collection (group, plurality) of zero or more distinct (different) objects. Set theory deals with operations between, relations among, and...
Boolean Matrices (all elements are 0 or 1) Operations on Boolean Matrices: –Let A and B be boolean Matrices –The boolean product of A (m x p) and B (p x n ) is (C = A B): C i,j = 1 if A i,j =1 and B k,j = 1 for some k, 1 k p C i,j =...

Operations that preserve convexity 保持凸性的操作 Intersection 取交 凸集的交集仍是凸集,PPT给的这个例子很妙,见板书里的证明。 Affine function 仿射函数 仿射函数更加一般的说法叫做线性函数。一个凸集经过仿射函数的变换后仍是凸集,反过来也是一样的,凸集经过逆变换之后仍是凸集。注意有可能实际方程的逆变换并不存...
