How to define a straight line that intersects as many rectangles as possible?
I am looking for an algorithm to solve this problem besides reinforcement learning and those that take a long time.
N rectangles are placed on the xy plane. How many rectangles can a straight line pass at the maximum?
Input
The number of rectangles is n.
The upper left coordinate of the rectangle of the number i is given by x [i], y [i].
Its width and height are specified by w [i], h [i].
Example
n
x[0] y[0] w[0] h[0]
x[1] y[1] w[1] h[1]
・
・
x[n-1] y[n-1] w[n-1] h[n-1]
The rule
- 0 <n <= 1000
- Each rectangle is placed at 0 <= x <= 10000, 0 <= y <= 10000.
- The coordinate must be whole.
- Width and height must be greater than 1 and an integer.
- The rectangles can overlap.
- A straight line can convey the vertices of rectangles to rectangles.
- The line must not go through (0, 0).
