Answer to Question #308540 in Operations Research for divya

Question

Which of the following is a correct statement?

 If the primal problem is in its standard form, dual variables will be non-negative.

Dual simplex method is applicable to an LPP, if initial basic feasible

solution is not optimum.

 Dual simplex method always leads to degenerate basic feasible solution.

If the number of primal variables is very small and the number of

constraints is very large, then it is more efficient to solve the dual rather

than the primal problem.
