### Given consumer grade hardware,what is a reasonable upper bound for size of search space?

There's a gacha RPG I'm trying to get better at. I estimate there are about 10^15 states for the 3 opening rounds of a match for which I am trying to evaluate damage output. The equations themselves ...

### Is there a computationally optimal point-in-polygon solution (for a dynamic scenario)?

I am approaching a problem where, among other things, I will have to repeatedly check if a point is within a (set of) polygon(s) in the 2D plane. the polygons are either convex or star-shaped with a ...

### Can we make at most 3 comparisons in the closest points algorithm instead of 7?

Let's say I am using the divide and conquer algorithm outlined here, but I only want to return the minimum distance. I understand why that algorithm puts an upper-bound at 7 but I think that can be ...

### Find The “Best” Permutation of Inputs to Maximize Sum of Functions (or approximate “best”)

The Problem (in words) I want to sort $N$ items where the value of item $i$ at position $p$ is given by the function $f_i(p)$. The "best" order for these items is the one that maximizes the ...
