Abstract
Recently, Fang proposed approximating a linear program in the Karmarka r standard form by adding an entropic barrier function to the objectiv e function and derived an unconstrained dual concave program. We prese nt in this note a necessary and sufficient condition for the existence of a dual optimal solution to the perturbed problem. In addition, a s harp upper bound of error estimation in this approximation scheme is p rovided.
