1953 United States mathematician G.B. Danzig for improved simplex method of accumulated rounding errors in each iteration, modified simplex method is proposed. Roughly the same basic steps, and the simplex method, the main difference is in the successive iterations no longer based on Gaussian elimin...
Applies to the coordinate transformation using Gaussian projection is calculated under Beijing, XI ' an 80-54 as well as coordinates in the cgcs2000 coordinate system, you can achieve the transformation of the coordinate system. Mapping and geographic information maps on the correction, the most bas...

BST tree is a binary search tree, but if multiple insertions, BST tree will be unbalanced or degenerate into a chain. So on the basis of BST tree and attached a heap of nature, the program uses the principle of minimum heap. Program code using VB6.0 write, since VB is not a p...
