[单选题]Why must randomized incremental construction converge for each insertion of the new point?
为什么说Delaunay三角剖分的RIC算法每次插入一个新的点一定会收敛？
AIt can't be guaranteed to converge (RIC算法插入新点并不能保证收敛)
BAngle vector will increase until it reach the upper bound (角度向量每次递增必会触及上界)
CTriangles are limited (因为三角形的个数是有限的)
DEach new insertion will infect only one triangle (每次插入一个新的点只会影响一个三角形)
