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.
