Comment #11 on issue 3658 by [email protected]: hydrogen.py very slow
http://code.google.com/p/sympy/issues/detail?id=3658
I bisected the slow running time. Basically, Aaron is right, the numerical
equality testing makes this hang and we should just remove them from
Relational.
Chronology:
sympy 0.7.1
Eq(i, i.doit()) remains unchanged (no automatic evaluation). It is used in
the example file to display an equality.
After commit c6cd70aa4ea9255dfbba337f581c57666daaf630 from this PR:
https://github.com/sympy/sympy/pull/1029
Eq(i, i.doit()) would just return True, defeating the intended use in the
example file to display an equality.
After commit 979e0aa50797d8f6dd3e15f73586cc9e84552d93 from this PR:
https://github.com/sympy/sympy/pull/1036
The example file starts taking very long.
