Data Science Asked on December 26, 2021
Suppose I have N
points (labeled 1, 2, ..., k, ..., N
) in D
dimensions. I’d like to choose the order of points such that, after each point, the volume of the convex hull is maximized.
In other words, the volume of the convex hull is a function of the number of points V(k)
(V(1) = V(2) = 0
), I’d like to choose the sequence of points {k_1, k_2, ..., k_N}
such that V(k) is maximized for each value of k.
The two algorithms I’ve thought of don’t seem very efficient:
O(N!)
O(N^p)
.Is there a cute, out of the box solution to this problem? Or a paper where someone has solved it already?
Genetic algorithms are often a good option for optimization problems, assuming it's not a requirement for the solution to be the best one but only to be "close enough".
