Piecewise linear Chebyshev approximation of planar curves
, 1983 Two algorithms for solving the piecewise linear Chebyshev approximation problem of planar curves are presented. The first one is for the case when the Chebyshev error norm in any segment does not exceed a preassigned value.

Numerical Chebyshev approximation by interpolating rationals
, 1972 The paper is concerned with the Chebyshev approximation of decay-type functions f ( x ) f(x) by interpolating rationals. The interpolating points are chosen to be the zeros of f (

Best Copositive Approximation [PDF]
, 1993 A theory of best copositive approximation including a "zero in the convex hull" characterization, alternation theorem, and strong uniqueness theorem is developed for a general n-dimensional Chebyshev subspace in C[a, b].

Linear Chebyshev approximation of complex-valued functions
, 1978 This paper is concerned with Chebyshev approximation by linear functions to complex-valued data. The problem is nonlinear, and we present a convergent algorithm for its solution.

, 2020 Teorija aproksimacija govori o što boljem prikazu, aproksimaciji jedne funkcije nekom drugom, jednostavnijom funkcijom. U nekim slučajevima možemo ocjeniti grešku aproksimacije, ali u najčešćim slučajevima ocjenu greške nemoguće je odrediti zbog manjka ...

Chebyshev polynomial approximation to approximate partial differential equations [PDF]
, 2008 This paper suggests a simple method based on Chebyshev approximation at Chebyshev nodes to approximate partial differential equations. The methodology simply consists in determining the value function by using a set of nodes and basis functions.

Best Co-approximation and Best Simultaneous Co-approximation in Fuzzy Normed Spaces
, 2013 The main purpose of this paper is to consider the t-best co-approximation and t-best simultaneous co-approximation in fuzzy normed spaces. We develop the theory of t-best co-approximation and t-best simultaneous co-approximation in quotient spaces.

Chebyshev Approximation of Discrete polynomials and Splines
, 1999 The recent development of the impulse/summation approach for efficient B-spline computation in the discrete domain should increase the use of B-splines in many applications.
