determine all values of a and ß for which
(Da‚ß) is infeasible. What does that mean about (Pa‚ß)?
(Da‚ß) is feasible, but not unbounded. What does that mean about (Pa,ß)?
(Da‚ß) is unbounded. What does that mean about (Pa,p)?
(Pa,ß) has multiple optimal solutions. (You reasoning should use complementarity slackness relation-
ships between primal and dual optimal solutions.)
