Interior point methods 25 years later

Gondzio, Jacek - In: European Journal of Operational Research 218 (2012) 3, pp. 587-601

Interior point methods for optimization have been around for more than 25 years now. Their presence has shaken up the field of optimization. Interior point methods for linear and (convex) quadratic programming display several features which make them particularly attractive for very large scale...
