`%K optimisation offsets robust approximation plane curves parametric curves global optimization problems interval arithmetic bisectors.`

`%X Most methods for computing offsets and bisectors of parametric curves are based on a local formulation of the distance to a curve. As a consequence, the computed objects may contain spurious parts and components, and have to be trimmed. We approach these problems as global optimization problems, and solve them using interval arithmetic, thus generating robust approximations that need not be trimmed.`
