Pareto Efficiency and Optimality This page is messed up While there is a relationship between Pareto Optimality and Pareto Efficiency they are different results I use Pareto optimality in my consulting see also Wiederhold Gio What is Your Software Worth Communications of the ACM Vol 49 No 9 Sept 2006 p 65 75 Some statements under P Efficiency belong under optimality as most of the first paragraph Pareto Optimality deserves its own page But now it redirects and I don t know how to change that
