1. An assumption of convex position can make certain computational problems easier to solve.
2. The book thickness adds an additional restriction, that all of the vertices be drawn in convex position, forming a circular layout of the graph.
3. Similarly, the minimum-weight triangulation is NP-hard for arbitrary point sets, but solvable in polynomial time by dynamic programming for points in convex position.
4. For instance, the traveling salesman problem, NP-hard for arbitrary sets of points in the plane, is trivial for points in convex position : the optimal tour is the convex hull.
5. However, the number of points necessary to find " k " points in convex position may be smaller in higher dimensions than it is in the plane, and it is possible to find subsets that are more highly constrained.
6. It's difficult to find convex position in a sentence. 用convex position造句挺難的
7. Equivalently, a strictly convex curve is a curve that intersects any line in at most two points, or a simple curve in convex position, meaning that none of its points is a convex combination of any other subset of its points.
8. The more famous ones are the elongated hair clip ( seen at the top of the " Various types of hair slides " image ) which was invented in 1972 by Marnie Bjornson ( cf . " Marnie Scrunch ", below ) and the simple " clips " hair-clip, which works by snapping the clip from a concave to convex position, springing it into a locked position, or opening it.
