Guide for creating Companion Proceeding at CEUR.WS

This document aims to streamline the creation of conference companion proceedings to be published on CEUR.WS. This is typically a time-consuming and labor-intensive task, but with careful management and leadership, we believe we can significantly reduce the effort required. In this document, we will first describe what is a companion proceeding and how it is … Read more

Computing Automorphic Numbers

In our lab, we like to tease each other with fancy riddles. In our kitchen, we have a large wooden box, filled with some chocolates and locked by a 4-digits lock. Those who crave for some sugar will just need to solve the riddle and unlock the box.
The last few riddles involved a particular family of numbers which are called automorphic, and the complexity of such riddles was increasing with the size of those numbers in terms of the number of digits. For instance, in the last riddle, we were asked to compute a number with 44444 digits, requiring an enormous computational power.
In this post, I will show how I developed the algorithm that allowed me to solve the riddle.
