<dc:description>This is the supporting material for the paper A Verified Implementation of the Berlekamp–Zassenhaus Factorization Algorithm by Jose Divasón, Sebastiaan Joosten, René Thiemann and Akihisa Yamada.
Abstract
We formalize the Berlekamp--Zassenhaus algorithm for factoring square-free integer polynomials in Isabelle/HOL. We further adapt an existing formalization of Yun's square-free factorization algorithm to integer polynomials, and thus provide an efficient and certified factorization algorithm for arbitrary univariate polynomials.
The algorithm first performs factorization in the prime field GF(p) and then performs computations in the ring of integers modulo pk, where both p and k are determined at runtime. Since a natural modeling of these structures via dependent types is not possible in Isabelle/HOL, we formalize the whole algorithm using locales and local type definitions.
Through experiments we verify that our algorithm factors polynomials of degree up to 500 within seconds.
Formalization
The formalization is part of the Archive of Formal Proofs for Isabelle 2018 within the entry The Factorization Algorithm of Berlekamp and Zassenhaus.

Experiments
One can rerun the experiments as follows:
Download and extract the attached file.
Inspect the path of the constant binary within the file experiments/Code_Old/Mathematica.hs whether it matches your Mathematica installation. Otherwise you can deactivate the Mathematica experiments by disabling the external factorization in experiments/Experiments/run_experiment.sh.
Compile experiments/Code_Old/Main and experiments/Code_New/Main with -O2
Invoke ./experiments/Experiments/run_experiments.sh
To turn the raw data into .csv-files and generated the Mathematica-graph, change to the experiments/Experiments directory and invoke ./time_tables_to_mathematica.sh
To get the pdf-file, paste the output of the previous command into the first line of the Mathematica-file journal_plot.nb
One can also run the experiments disabling some of the optimizations by means of the files Code_New_No_{...}/Main.hs
In addition, the Isabelle file Generate_Code.thy generates the Haskell sources.
The following table contains all the experiments of Figure 1 in the article.
