This very readable book presents an elementary introduction to linear programming in a refreshing, often humorous style. Requiring no math beyond high-school algebra, the book shows how linear programming can help anyone reach the optimum solution for a host of diverse problems. Chapter One introduces the basic concepts of linear programming and discusses its relationship to other mathematical models. Chapter Two discusses the formulation of linear-programming problems, including detailed treatment of problems involving diet, catering, assignment, and activity analysis. Chapter Three briefly introduces solution techniques for linear-programming problems, emphasizing the graphical approach.

In  and , the normal system Face algorithms were originally published in Chapters 22 and 23 in the monograph Linear Programming Computation . They are natural developments of the author's research results over the years, including those presented in - , as summarized in the book also see Yangyang Shi, Leihong Zhang and Wenxing Zhu  for an overview.

Mar The face algorithm for solving LP problems is proposed with very favorable computational results, mainly because it uses the orthogonal projection of the negative objective gradient on the relevant null space as its search direction . Nevertheless, the algorithm would not be amenable for solving large sparse problems, since it handles involved normal system via Cholesky factorization or, alternatively, inversion of the coefficient matrix. Instead, in this paper, we propose a new face method using Gaussian elimination to lay a basis for an implementation, presented in a subsequent paper. The assumption on the rank of A is not essential, and can be dropped. A distinguished feature of the face algorithm  for solving LP problem is that it uses the orthogonal projection of the gradient of the objective function on the null space as its search direction.

This is why it is so fast. The resulting formulas appear to be simpler that those for updating its counterpart in the dual face context . In order to simplify computation, we will handle the so-called "reduced problem" . This special form can be obtained equivalently from 1.

Feb A revision of the face algorithm is presented. In this case, the dual problem is unbounded . Since the preceding Algorithm is theoretically equivalent to the face algorithm described in  , the following results is evident.

The invalid Archimedean axiom is improved by replacing it with Archimedes' theorem. The fundamental theorem of set theory holds.

The number of algebraic numbers is counted in general and asymptotically up to a given degree, and a method for counting the elements of infinite sets is specified. The real and complex numbers are re-characterised by extending them to infinity.

The introduction of the concepts of exact integrals and exact differentials allow non-continuous functions to be integrated and differentiated on conventionally un- measurable sets, in some cases without requiring the notion of holomorphicity, while continuing to satisfy key theorems and other elementary properties.

The Cauchy product has to be corrected.

The concepts of convergence and continuity are made precise and reformulated for real and complex sets. The concepts of open and closed sets are reduced to absurdity. The axioms of Euclidean geometry are reviewed, revealing some of them to be false or redundant.

Toeplitz' conjecture is refuted and Fickett's conjecture is proven. In the field of linear programming, first the diameter theorem for polytopes is proven. The well-known exponential simplex algorithm with a perturbation method for overcoming the problem of multiple vertices is confronted with the polynomial intex method. Finite and infinite algebraic and transcendental numbers are distinguished, determined, and a statement about their distances is established.
