Optimising the four-arc approximation to ellipses

The four-arc approximation to ellipses is important for such applications as image processing, curve fitting, NC machining, cam design, and collision avoidance. As approximation quality is evaluated in engineering usually by the maximum error, this paper aims to minimize the maximum error, starting...
