I just tried it in my computer, to ensure I did not pass any wrong
information :-)
But I first inspected the contents of
"devel/sage/doc/en/reference/sage/categories/examples/algebras_with_basis.rst"
I am not sure what is the correct procedure to view the output in
text mode, so, I just opened
file:///usr/share/sage/devel/doc/output/html/en/reference/sage/categories/examples/algebras_with_basis.html
in firefox. That is the path in my rpm (/usr/share/sage/sage is a
symlink to the system wide python site dir, so I use the doc in a
directory below).
Then, I did a cut&paste of the examples, commenting the expected
results, i.e.:
-%<-
sage: A = AlgebrasWithBasis(QQ).example(); A
# An example of an algebra with basis: the free algebra on the
generators ('a', 'b', 'c') over Rational Field
sage: A.algebra_generators()
# Family (B[word: a], B[word: b], B[word: c])
sage: A = AlgebrasWithBasis(QQ).example()
sage: A.one_basis()
# word:
sage: A.one()
# B[word: ]
sage: A = AlgebrasWithBasis(QQ).example()
sage: Words = A.basis().keys()
sage: A.product_on_basis(Words("acb"), Words("cba"))
# B[word: acbcba]
sage: (a,b,c) = A.algebra_generators()
sage: a * (1-b)^2 * c
# B[word: abbc] - 2*B[word: abc] + B[word: ac]
-%<-
And here is a cut&paste of the session in a fresh xterm:
-%<-

Note that it took quite some time to get the sage prompt, just keep
a look in 'top';
if memcheck-* is at almost 100% it is running, but you should already know about
that :-)
But I did this test on i686, using system valgrind. When I told it
could be polybori,
and require that patch, also note that I build polybori with system boost....
But this response may still be misleading, as I did the test on sage
4.4 (I will
probably skip 4.4.1 and work on a 4.4.2 package or newer once Mandriva 2010.1
is released...)
