A question about IPX algorithm

[tusiqi1]

I'm not sure if I'm right.

I found that the IPX algorithm does not use a central path, and the self-dual nonlinear system of equations. Why solve for KKT conditions directly? Can the addition of these two techniques accelerate LP solving?

IPX does follow the central path
