This is a survey paper summarizing recent research aimed at finding guaranteed optimal algorithms for solving problems in Multiview Geometry. Many of the traditional problems in Multiview Geometry now have optimal solutions in terms of minimizing residual imageplane error. Success has been achieved in minimizing L2 (least-squares) or L∞ (smallest maximum error) norm. The main methods involve Second Order Cone Programming, or quasi-convex optimization, and Branch-andbound. The paper gives an overview of the subject while avoiding as far as possible the mathematical details, which can be found in the original papers. J.E.Littlewood: The first test of potential in mathematics is whether you can get anything out of geometry. G.H.Hardy: The sort of mathematics that is useful to a superior engineer, or a moderate physicist has no esthetic value and is of no interest to the real mathematician.
