This paper is a study of several problems of best approximation to a given function in a normed linear space from a convex subset of a finite-dimensional subspace. Specific problems treated are ...
Approximation theory and asymptotic methods form a foundational framework that bridges classical ideas with modern numerical analysis, enabling researchers to obtain practical, near‐optimal solutions ...
