The Optimal Recovery problems seek to construct and characterize the best method of approximation of a certain functional in different classes of functions, considering some data that are available. Several classical problems such as interpolation, uniform approximation and numerical integration can be approached in this context. The object of study is the general theory of optimal recovery which provides appropriate mathematical tools for the analysis and comparison of error of different methods.
