Abstract: | Summary. Bermúdez-Moreno 5] presents a duality numerical algorithm for solving variational inequalities of the second kind. The performance
of this algorithm strongly depends on the choice of two constant parameters. Assuming a further hypothesis of the inf-sup type, we present here a convergence theorem that improves on the one presented in 5]: we prove that the convergence is linear,
and we give the expression of the asymptotic error constant and the explicit form of the optimal parameters, as a function
of some constants related to the variational inequality. Finally, we present some numerical examples that confirm the theoretical
results.
