QUESTION
In a past question, Is there a CAS for Pharo?, I asked about a Computer Algebra System for Pharo, and people pointed to Domains, a port of Mathematics from CUIS smalltalk, that is part of PolyMath project. I suceeded installing PolyMath in Pharo 8, running the following code in the playground, as adviced in https://github.com/PolyMathOrg/PolyMath:
...ANSWER
Answered 2021-Mar-02 at 08:24Once you load polymath, you will have all packages available to load. The tool used to load/save packages in Pharo is called iceberg (is a git client). You can find it in the menu "tools" in Pharo 8 or in "browse" in Pharo 9.

QUESTION
I'm looking to include the results of multiple statistical tests in a faceted ggplot chart.
I've found lots of excellent examples (like this) on how to include something similar in a title or annotation, however, my interest lies in including it as a text annotation so that I can show the results of many tests on one figure.
I have been able to do this using standard text annotations, however I want to present my results using polymath
/expressions
so that I can produce an annotation that follows the APA style guide as implemented in the package [ggstatsplot]
1, see example below:
I've included code for a reproducible example below using the diamonds
data from ggplot2
. Some of the things that I have tried include:
- trying to store
bquote
andexpression
objects as columns in thewilcox_stats
object — however dplyr doesn't seem to like it - trying to call this all from
ggplot
— however it got quite messy trying to exclude all the annotations thatgeom_text
wanted to print
Any assistance or pointers you can provide would be much appreciated.
...ANSWER
Answered 2020-Apr-26 at 12:36I'd probably create the expressions using paste, (tbh, because I find it easier to include variables).
I have slightly shortened the code and also not used your full expression, but I think it should hopefully be enough to get the idea.
QUESTION
I've implemented algorithms for finding an inverse of a polynomial as described at onboard security resourses, but these algorithms imply that GCD of poly that I want to invert and X^N - 1 is 1.
For proper NTRU implementation I need to randomly generate small polynomials and define if their inverse exist, for now I don't have such functionality. In order to get it work i tried to implement Euclidean algorithm as described in documentation for NTRU Open Source project. But I found some things very inconsistent which bugs me off. Division and Euclidean algorithms can be found on page 19 of named document.
So, in division algorithm the inputs are polynomials a and b. It is stated that polynomial b must be of degree N-1.
Pseudocode for division algorithm (taken from this answer):
...ANSWER
Answered 2019-May-26 at 08:59I accidentally googled the answer. I don't really need to calculate GCD to pick a random invertable polynomial, I just need to choose the right amount of 1 and 0 (for binary) or -1, 0 and 1 (for ternary) for my random poly.
Please, consider this question solved.

Install polymath
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
