Algorithm to minimize an expression
If I have a constraint like $y_1 + y_2 +\dots + y_n = k$ for positive integers $y_i$, how would I minimize
$$\quad\frac{x_1 }{ y_1} + \frac{x_2 }{ y_2} + \frac{x_3 }{ y_3} + \dots + \frac{x_n }{ y_n} …

Finding all possible bottom-most overlapping rectangles on a table
Let's say that I'm given a $n\times n$ ($n\leq 1000$) grid (more of like a table) and I color the grid with $n^2$ rectangles, each of a different color (let's say they have colors 1 to $n^2$ for simpl …
