Given two polygons P and Q, with n P and n Q extreme points.
Assume P and Q are both given with their list of extreme points in, e.g., the CW order, starting with an arbitrary extreme point.
What is the best complexity of their intersection check, i.e., checking whether they intersect or not.

Given two polygons P and Q, with n P   and n Q   extreme points. 
 Assume P and Q are both given with their list of extreme points in, e.g., the CW order, starting with an arbitrary extreme point. 
 What is the best complexity of their intersection check, i.e., checking whether they intersect or not.

Accepted Answer

O(n P  + n Q )

Answer

O( max {n P  log n P ,  n Q  log n Q  })

Answer

O(n P  log n P  + n Q  log n Q  )

Answer

O( max {n P  , n Q } )
