Title
Large step volumetric potential reduction algorithms for linear programming
Abstract
We consider the construction of potential reduction algorithms using volumetric, and mixed volumetric — logarithmic, barriers. These are true “large step” methods, where dual updates produce constant-factor reductions in the primal-dual gap. Using a mixed volumetric — logarithmic barrier we obtain an <img src="/fulltext-image.asp?format=htmlnonpaginated&src=YLQ578T431641661_html\10479_2005_Article_BF02206828_TeX2GIFIE1.gif" border="0" alt=" $$O(\sqrt {nmL} )$$ " /> iteration algorithm, improving on the best previously known complexity for a large step method. Our results complement those of Vaidya and Atkinson on small step volumetric, and mixed volumetric — logarithmic, barrier function algorithms. We also obtain simplified proofs of fundamental properties of the volumetric barrier, originally due to Vaidya.
