In this paper, we analyze the exponential method of multipliers for co
nvex constrained minimization problems, which operates like the usual
Augmented Lagrangian method, except that it uses an exponential penalt
y function in place of the usual quadratic. We also analyze a dual cou
nterpart, the entropy minimization algorithm, which operates like the
proximal minimization algorithm, except that it uses a logarithmic/ent
ropy ''proximal'' term in place of a quadratic. We strengthen substant
ially the available convergence results for these methods, and we deri
ve the convergence rate of these methods when applied to linear progra
ms.
