Chebyshev approximation linear programming
Webbe considered. Two algorithms for obtaining best approximations, the linear inequality method and the dynamic programming method, will be discussed. Finally, some examples will be given of functions approximated by 'the ratio of linear forms. II. A Chebyshev problem. Before describing the general problem, let us consider a specific example in ... Websolve approximation problems using di erent techniques. We also compare approximation in the uniform norm to the well-known approximation in the L2-norm. This will give a complete overview of the subject. Since this thesis is all about Chebyshev, in chapter 2 we will tell who Cheby-shev was and why he was interested in approximation theory. In ...

Webpurposes to the familiar Chebyshev approximation criterion. This gains access to the rich legacy on Chebyshev approximation techniques, to which we add some new methods for cases of particular interest in mathematical programming. Some results relating to post- computational bounds are also obtained.
