A note on degeneracy in linear programming
An interesting question is raised in [I] about the role of degeneracy in the worst-case complexity of the randomized simplex algorithm. It is well known that every linear programming problem can be perturbed into a non-degenerate problem [3, 41. However, it is interesting to know how hard the problem is of "exiting" a degenerate vertex in a direction that improves the objective function value. ...
متن کاملA Note on Approximate Linear Programming
M Serna recently proved that approximating linear programming is log space complete for P This note shows a direct reduction of the exact problem to Serna s approximate one Consider the problem given A Z n and b Z decide whether D fx QjAx b x g If D then there exists an x D such that x e where L is the length of the input and e T Z see e g Consider the problem P Maximize t subject to Ax t b x t...
متن کاملA NOTE ON THE ZIMMERMANN METHOD FOR SOLVING FUZZY LINEAR PROGRAMMING PROBLEMS
There are several methods for solving fuzzy linear programming (FLP)problems. When the constraints and/or the objective function are fuzzy, the methodsproposed by Zimmermann, Verdegay, Chanas and Werners are used more often thanthe others. In the Zimmerman method (ZM) the main objective function cx is addedto the constraints as a fuzzy goal and the corresponding linear programming (LP)problem w...

15 صفحه اولNote on Practical Dynamic Programming
Since we convert the original sequential problem into a collection of small problems, it is important to make sure that the solution to each of the small problems is actually optimal in the original problem. In other words, the optimal choice in each of the two-period problem must be globally optimal to justify the transformation. Richard Bellman, the inventor of the dynamic programming method,...
