 intersection algorithm
 Any reliable implementation of a line intersection algorithm has to address the limitations of a discrete computational environment. In order to minimize both the influence of the coordinate frame and information loss we suggest a nested thicket representation for random variables and a corresponding intersection algorithm. We show that the weighted two matroid intersection algorithm determines the maximum costK-forest cover. Upper bounds for the Type I error probabilities are established for general k1 and k2 using the concept of partitions and a union-intersection algorithm. We have presented a surface approximation technique that is based on an iterative ray-surface intersection algorithm. 更多
