Abstract
We give two results related to Gonzaga's recent paper showing that low er bounds derived from the Todd-Burrell update can be obtained by solv ing a one-variable linear programming problem involving the centering direction and the affine direction. We show how these results may be u sed to update the primal solution when using the dual affine variant o f Karmarkar's algorithm. This leads to a dual projective algorithm.
