Solution to the projection problem would typically be a two-stage algorithm. The first stage would use a global-type algorithm to find a solution interval, and a faster local algorithm like Newton-Raphson would kick in once the solution interval is obtained. Typically the first stage algorithms are slow - variations of secant method, or steepestphaedrushttps://www.blogger.com/profile/06982170581581509504noreply@blogger.com
