- In computational geometry, the potato peeling or convex skull problem is a problem of finding the convex polygon of the largest possible area that lies within a given non-convex polygon. It was posed independently by Goodman and Woo, [1] [2] and solved in polynomial time by Chang and Yap [3]. The exponent of the polynomial time bound is high, but the same problem can also be accurately approximated in near-linear time [4].
