Focusing on reliable, compact algorithms for computational problems, this book considers specific mathematical problems of wide applicability, develops approaches to a solution and the consequent algorithm, and provides the program steps. It emphasizes useful applicable methods from various scientific research fields, ranging from mathematical physics to commodity production modeling. This edition now presents program steps as Turbo Pascal code, includes more algorithmic examples, and contains an extended bibliography. The accompanying software includes algorithm source codes, driver programs, example data, and utility codes to aid in the software engineering of end-user programs.
