Jarvis-March(P) $\;\;\;\;\;$; P = $\langle p_0, .., p_{n-1} \rangle$ points
$\;\;\;\;\;$p = p₀, the lowest point
$\;\;\;\;\;$while p not highest point
$\;\;\;\;\;$ $\;\;\;\;\;$find point p_m with minimum polar angle from $p \longrightarrow$
$\;\;\;\;\;$ $\;\;\;\;\;$add p_m to convex hull
$\;\;\;\;\;$ $\;\;\;\;\;$p = p_m
$\;\;\;\;\;$while $p \neq p_0$
