_{p}(1<p<~) problem are considered. The algorithms are also constructed for the L

_{1}problem as the extreme case of the L

_{p}problem. Numerical results are reported for some well-known examples, which show that the algorithms are efficient. Numerical comparisons are made between these algorithms and others.

_{p}-approximation problem is a basic problem in approximation theory and optimization. This problem is normally solved by Newton-type methods which are complicated by the nondifferentiability of the gradient function for p [1,2). This paper discusses a scheme and its implementation for solving this problem by a method of analytic centers, which provides a unified treatment for...
