These reports and the web pages themselves were written in LaTeX using TeXLive distribution and compiled to HTML using TeX4ht.
These reports show the result of using full CAS test suite on different CAS’s at same time. This compares how one CAS perform against another.
The test suite uses the full Rubi test files provided thanks to Albert Rich.

These reports show the result of using same test suite on different versions of same CAS. Only Maple, Mathematica and Rubi are used. This is for regression testing to find how different version of the same CAS improved over the years. The test suite used is the lite version of the full CAS intergation tests. It contains smaller number of integrals compared to the full test suite used above.
This zip file contains the raw input tests used which was obtained from Rubi web site.
Uses same zip file as above for input.

The following diagram gives a high level view of the current test build system.
I really need a faster PC with much more RAM !
This below shows example of CAS suddenly consuming all RAM in PC, and I had to terminate the process, since it did not time out as instructed, and just hanged.

To install fricas on Linux Manjaro sudo pacman -S sagemath.
in case of error while installing the package, try sudo pacman -Rs sagemath and then repeat the previous command
If copy paste does not work between windows and Linux VBox, try VBoxClient --clipboard
To use Fricas online, go to http://fricas-wiki.math.uni.wroc.pl/SandBox
Go to bottom of page, type
\begin{axiom} setSimplifyDenomsFlag(true) integrate(sin(x),x) \end{axiom}
Then click the preview button
to send email to supprt group use fricas-devel@googlegroups.com
To download go to https://sourceforge.net/projects/fricas
To installl on Linux Manjaro, type yay -S fricas . Do not use the Manjaro GUI package manager, it always gives build error for some reason. Make sure to install yay first using GUI manager.
Make sure when installing Linux on VBox, to add second CPU to configuration of VBox. i.e. do not use ONE CPU (which is default). There is a bug in fricas installation which makes it fail due to use of multi-threading if only one CPU exist. This should be fixed in future, but just in case.

For Fricas, use these commands to get 1D plain text output
Otherwise the output will go to console in 2D. To get Latex output do
To record console session to file, use (from https://github.com/daly/axiom/blob/master/faq)
Like this
To send Latex output to file do
To turn off, just do )set output tex off. Make sure to tex on first. To send back to console, do )set output tex console
To read commands from file do
To read an input file into Axiom, use the )read system command. read For example, you can read a file in a particular directory by issuing

Some hints below thanks to Waldek Hebisch http://mathforum.org/kb/message.jspa?messageID=9791385
copied here so easy for me to get to:
1. How to measure CPU time used from the int call? (3) -> )set messages time on (3) -> integrate(x^(3/2)/sqrt(1 + x^5), x) Type: Union(Expression(Integer),...) Time: 0.06 (EV) + 0.00 (OT) = 0.06 sec That is command ')set messages time on' tell FriCAS to print time needed to execute following command. The (EV) part means actual computation (OT) printing and at the end there is total 2. How to measure leaf count/size of result? (Maple and Mathematica have build in function to do this) That is a bit tricky. FriCAS (like Axiom) has quite different representation of expressions tham Maple or Mathematica. In FriCAS expression is a quotient of two polnomials, with variables beeing kernels: (13) -> f := exp(x^3 + 1/x) + 1 (14) -> numer(f) 4 x + 1 ------ x (15) -> denom(f) (16) -> variables(numer(f)) 4 x + 1 ------ x (16) [%e ] Type: List(Kernel(Expression(Integer))) Time: 0.00 (OT) = 0.00 sec From FriCAS point of view natural measure of size is number of monomials in numerator and denominator: (17) -> numberOfMonomials(numer(f)) (17) 2 (18) -> numberOfMonomials(denom(f)) (18) 1 but this may underestimate size because kernels may be big. Also internally given kernel is stored only once, but in printed output it may appear several times. It is possible to traverse expression is somewhat tree like manner, so it is possible to give better approximation to say Maple result, but that would require investigating what Maple is doing. I personally never used Maple node count so I do not know it this is simple or if there are some traps. 3. How to check if int passed or failed? Aborted? nil result? etc.. integrate may produce an error (in particular it will do so if it can not decide if integral is elementary). Or may produce unevaluated integral. Or normal result. At programistic level it is possible to catch errors, but a bit tricky, If you look at printed output, than errors are reasonably easy to match via a regex: (22) -> integrate(1/sqrt(exp(x) - x + 1), x) integrate: implementation incomplete (constant residues) the '>> Error' part indicates error. Unevaluated integrals always have integral sign at top level. FriCAS never returns partial results, so text match is relatively easy. Or you may use code like: test_int(f) == res : Union(Expression Integer, LE) res := integrate(f, 'x) res0 : List Expression Integer := res case Expression Integer => [res::(Expression Integer)]@(List Expression Integer) res case List Expression Integer => res::(List Expression Integer) error "test_int: impossible 1" for ri in res0 repeat #(kernels ri) > 0 and is?(operator first kernels ri, 'integral) => print("Unevaluated integral"::OutputForm) Note1: this is part extracted from bigger test script, I did not test it alone. Note2: FriCAS may either return list of results or a single result. Middle part converts this to have always a list (typically of length 1). The last part is a loop so that all solutions can be examined. It you only want to know if result is evaluated, than loop is not needed: more than one result means that integral is evaluated. Note3: In FriCAS testsuite I use a bit different test for evaluated integrals. Namely, FriCAS can do useful computations on unevaluated integrals and in particular unevaluated integrals may appear in the argument to integrate. Such unevaluated integrals of course may propagate form input to the output. The test above may misclasify such integral as unevaluated, while better test checks that unevaluated integral came from the input. 4. And most importantly, how to export the result (if it passed) to a plain text file in _Latex_ format? (24) -> )set output tex on (24) -> integrate(exp(x)*exp(1/(exp(x)+1)-x), x) Here one have to decide what to do with errors. Without error trapping error will abort currently executing function and propagate to top level (up to command line). After doing: )set break resume after error FriCAS will continue executing file from next command (but still abort current command). If you need real loop then I can provide error catcher, but it is a bit more complicated than snippets above. Waldek Hebisch

To obtain a Rational in SymPy, one of these methods must be used: >>> from sympy import Rational >>> Rational(2, 7) 2/7
In python/sympy, to loop using index 1, can use this:
>>> for num,val in enumerate(sol,start=1): ... print("root number {} is {}".format(num,val))
For timeout in recent python, on windows, this seems to work
from subprocess import STDOUT, check_output output = check_output('dir', shell=True, stderr=STDOUT, timeout=5) print(output)
