Simplex method 2 phase example
WebbFor this example, use these linear inequality constraints: A = [1 1 1 1/4 1 -1 -1/4 -1 -1 -1 -1 1]; b = [2 1 2 1 -1 2]; Use the linear equality constraint . Aeq = [1 1/4]; beq = 1/2; Set these bounds: lb = [-1,-0.5]; ub = [1.5,1.25]; Use the objective function . f = [-1 -1/3]; Solve the linear program. x = linprog (f,A,b,Aeq,beq,lb,ub) WebbTwo-Phase Method Steps (Rule) Step-1: Phase-1 a.
