Talk:Cutting-plane method
From Wikipedia, the free encyclopedia
I'm sure the mathematical presentation of cutting planes in this article makes sense to someone (other than the author) but it makes no sense to me. I came to wikipedia because I am not familiar with cutting planes, though I get the basic idea. Then I see a sequence of formulae, with practically no explanation of what they are supposed to mean. What is b-bar? (with an overbar) What does xf stand for? What is the point that the sequence of formulae is trying to make?
