Dear Prof. Shen,

regarding your e-mail of complaint, we apologize for our deplorable
mistake. In the original draft of our paper we clearly cited the work
[1], but, unfortunately, the citation was involuntarily eliminated in
the camera-ready version [2]. This was due to a revision carried out
in order to fit the paper on the strict page constraints.
Nevertheless, the work of  Menczer, Akavipat e Wu is clearly cited
(although with an inaccuracy) and widely discussed in a successive
version of our work [3], as follows:

"Finally, Menczer et al. [11] propose a local adaptive routing
algorithm that dynamically modify the network topology toward a small
world structure, using a learning scheme similar to that considered in
this paper. However, they design their protocol with the aim of
supporting an alternative model for peer-based Web-search, where the
scalability limitations of centralized search engines can be overcome
via distributed Web crawling and searching."

In attachment you can find the pdf version of the paper [3].

We apologize again for what happened and for any inconvenience this
may have caused you and the authors.

Sincerely yours,

--
