Chapter Chapter 3 in Linear Programming, 2014, pp 25-37 from Springer

Abstract: Abstract In the previous chapter, we discussed what it means when the ratios computed to calculate the leaving variable are all nonpositive (the problem is unbounded). In this chapter, we take up the more delicate issue of what happens when some of the ratios are infinite (i.e., their denominators vanish).
