RT Journal Article T1 A Clustering Perspective of the Collatz Conjecture A1 Tenreiro Machado, José António A1 Galhano, Alexandra A1 Cao Labora, Daniel K1 Multidimensional scaling K1 Collatz conjecture K1 Clustering methods AB This manuscript focuses on one of the most famous open problems in mathematics, namely the Collatz conjecture. The first part of the paper is devoted to describe the problem, providing a historical introduction to it, as well as giving some intuitive arguments of why is it hard from the mathematical point of view. The second part is dedicated to the visualization of behaviors of the Collatz iteration function and the analysis of the results PB MDPI YR 2021 FD 2021 LK http://hdl.handle.net/10347/24434 UL http://hdl.handle.net/10347/24434 LA eng NO Mathematics 2021, 9(4), 314; https://doi.org/10.3390/math9040314 NO The work of D.
