Codeforces 460e Roland and Rose (violent)

Link: codeforces 460e Roland and Rose N Integer Points are selected in the local area where the origin is the center and the radius is R, so that the sum of squares of the distance between the two points is the largest. Solution: The maximum R value is 30. In fact, there are only 12 Integer Points with the largest distance from the center of the circle, and the enumeration is directly violent. #include Codeforces 460e

I thought it was a tree-like DP, where DFS is located according to the tree-like DP method. The result is wa, because it has a directed ring, not a tree, do not use the tree-like method in the case of loops. The breakthrough point of the question is to use vertices to represent the maximum length of the end of an edge with this vertex after the edge is sorted, because the edge is sorted from small to large, therefore, the side appended must be smaller than the front side.

Concave or concave, which is called the opposite, concave upward and downward

derivative is F ' (x) = 15x2 + 4x−3 (using Power Rule) the second Deriv Ative is F ' (x) = 30x + 4 (using Power Rule) and 30x + 4 are negative up to X =−4/30 =−2/15, and positive from there onwards. So:f (x) is concave downward up to X =−2/15 f (x) are concave upward from x =−2/15 on Note:the point where it changes is called a inflection point.
