Consider the linear program minimize subject to z = c²x Ax≤ b e'x = 1 XIX-120, x, free, where e = (1..... 1), b and c are arbitrary vectors of length n, and A is the matrix with entries a₁ = din = = 1 for i ...n and all other entries zero. Use the I to eliminate the free variable x, from the linear program (as in constraint ex = the previous problem). Is this a good approach when # is large?

2.5. Consider the linear program minimize subject to z = c'x Ax ≤ b e'x = 1 X₁X120, x,, free, where e = (1..... 1). b and c are arbitrary vectors of length n. and A is the matrix with entries a₁ = an = = 1 for i = 1,...,n and all other entries zero. Use the constraint ex = 1 to eliminate the free variable x,, from the linear program (as in the previous problem). Is this a good approach when n iş large?
