1. Classic convex hull algorithm. JAVA language. Absolutely correct.

2. Instead of constructing a convex hull, we could construct a bounding box around the solid.

3. Being a basic structure of computational geometry, convex hull is important to data analysis of GIS.

4. In practice, ROC Convex Hull ( ROCCH ) method which combines techniques from computational geometry is used.

5. That is multi - direction extreme value approximate convex hull algorithm, and is called MDEV for short.

6. In addition, we prove the performance ratio of the convex hull insertion for the traveling salesman problem in Euclidean plane has the upper bound about a logarithmic function of the number of nodes.

7. The key problem of direct allocation method is to determine the intersection of the desired objective vector with the convex hull of the attainable moments set(AMS).

8. At the same time it has the local controllability inherited from convex hull.

9. An improved image recognition and registration algorithm based on convex hull and affine invariant was presented.
