The amount of time resources (number of atomic operations or machine steps) required to solve a problem expressed in terms of input size. If your question concerns algorithm analysis, use the [runtime-analysis] tag instead. If your question concerns whether or not a computation will *ever* finish, use the [computability] tag instead. Time-complexity is perhaps the most important sub-topic of complexity theory.

Maximal subsets of a point set which fit in a unit disk

Suppose that there are a set $P$ of $n$ points on the plane, and let $P_1, \dots, P_k$ be distinct subsets of $P$ such that all points in $P_i$ fits inside one unit disk for all $i$, $1\le i\le k$. Mo …

How to solve this asymptotic complexity problem?

$f_3(n)$ has the highest asymptotic time since it is an exponential function. Although it is $(1+\epsilon)^n$ and might seem very tiny in terms of growth, there exists a real number $m$ where it grows …

Sorting numbers in $O(1)$

Here is an experiment I came up with (I don't have sufficient material to make it): Say that, you have a list of $n$ numbers $L = \{l_1, l_2, ..., l_n\}$. And you have bars representing those numbers …
