Abstract

In this paper, we explain how Robert Langdon, a famous Harvard Professor of Religious Symbology, brought us to decipher the Code of the Origins. We first formalize the problem to be solved to understand the Code of the Origins. We call it the Scatter Problem (SP). We then show that the SP cannot be deterministically solved. Next, we propose a randomized algorithm for this problem. The proposed solution is trivially self-stabilizing. We then show how to design a self-stabilizing version of any deterministic solution for the Pattern Formation and the Gathering problems.
