Abstract
(e goal of this paper is to propose a dual version of the direct cosine simplex algorithm (DDCA) for general linear problems. (e
proposed method has not artificial variables, so it is different from both the two-phase method and big-M method. Our technique
solves the dual Klee–Minty problem via two iterations and solves the dual Clausen problem via four iterations. (e power of the
proposed algorithm is evident from the extensive experimental results on benchmark problems adapted from NETLIB. Preliminary
results indicate that this dual direct cosine simplex algorithm (DDCA) reduces the number of iterations of the twophase
method.
