Dictionary of Algorithms, Data Structures, and Problems - A good collection of keywords definition, and links to further information and implementations. Unlike the ordinary sensitivity analysis, the construction presented here allows us to analyze any type of changes including dependent, independent, and multiple changes in both the RHS values and the cost coefficients. NEOS Guide - A guide to optimization including software, and case studies. OR Tutorial Notes - A set of tutorial notes giving an introduction to operations research from J E Beasley at Imperial College in London. Tools for LP Modeling Validation - This Web site introduces you to what can go wrong in the process of building a linear programming model.
Potential problems exist which affect any linear programming application.
Solutions may be infeasible or unbounded, or there may be multiple solutions. Degeneracy may also occur. These and other pitfalls are not of much deficiencies of linear programming as they are situations of which the decision maker should be cognizant. Toward the Simplex Method - The web site contains notes on the development of simplex algorithm from the algebraic methods of solving linear programs, together with pivoting row operations needed to perform the simplex iterations. A Tutorial on Integer - A good source to learn Integer Optimization solution algorithms and their applications.
