An important problem that arises in many scientific and engineering applications
is that of approximating limits of infinite sequences which in most instances
converge very slowly. Thus, to approximate limits with reasonable accuracy, it
is necessary to compute a large number of terms, and this is in general costly.
These limits can be approximated economically and with high accuracy by applying
suitable extrapolation (or convergence acceleration) methods to a small number
of terms. This book is concerned with the coherent treatment, including
derivation, analysis, and applications, of the most useful scalar extrapolation
methods. The methods it discusses are geared toward problems that commonly arise
in scientific and engineering disciplines. It differs from existing books on the
subject in that it concentrates on the most powerful nonlinear methods, presents
in-depth treatments of them, and shows which methods are most effective for
different classes of practical nontrivial problems; it also shows how to
fine-tune these methods to obtain the best numerical results. This
state-of-the-art reference on the theory and practice of extrapolation methods
will interest mathematicians interested in the theory of the relevant methods as
well as giving applied scientists and engineers a practical guide to applying
speed-up methods in the solution of difficult computational problems. Avram Sidi
is Professor is Numerical Analysis in the Computer Science Department at the
Technion-Israel Institute of Technology and holds the Technion Administration
Chair in Computer Science. He has published extensively in various areas of
numerical analysis and approximation theory and in journals such asMathematics
of Computation, SIAM Review, SIAM Journal on Numerical Analysis, Journal of
Approximation Theory, Journal of Computational and Applied Mathematics,
Numerische Mathematik, and Journal of Scientific Computing. Professor Sidi's
work has involved the development of novel methods, their detailed mathematical
analysis, design of efficient algorithms for their implementation, and their
application to difficult practical problems. His methods and algorithms are
successfully used in various scientific and engineering disciplines.
