Let P be a simple polygon with m vertices, k of which are
reflex, and which contains r red points and b blue points in its
n = m + r + b. A
ham-sandwich geodesic is a shortest path in P between two points
on the boundary of P that simultaneously bisects the red points and the
blue points. We present an O(n log k)-time
algorithm for finding a ham-sandwich geodesic. We also show that this
algorithm is optimal in the algebraic computation tree model when
parameterizing the running time with respect to n and k.
