Professor Roger Fletcher FRS FRSE
Roger Fletcher was one of the world’s leading numerical analysts. He was best known for his work in optimization, where he made many innovative and fundamentally important contributions. He also wrote numerous computer programmes based on methods which he developed, and many of these are widely used. Optimization (also referred to as mathematical programming) is essentially concerned with the calculation of the best or optimal values of a number of variables over a range of possibilities. Therefore it is a field which crosses subject boundaries and has many applications, for example to the improvement of drug design, the minimization of production costs, the maximization of power output, the determination of the lowest energy configuration. As a consequence, Roger’s work was known, appreciated and widely used across science, engineering and business. Read full obituary
