Testing export and normalization of isles¶

When we have variables such as $A: Type$, $a : A$ and $B: Type$, we test whether we correctly:

export equations, so that variables end up in islands
normalize isle names.

This time the test is more refined. Namely,

We generate with the equations after exporting and just $Type$ as the initial distribution.
We check that all terms are independent of the variables.
Generate with equations after normalization.
Make the same tests.
Also test if the distribution after normalization is approximately the same as before.

Next conclusion¶

terms are generated correctly
however, this does not test deeper generation, for which we must generate with the equations.

Preliminary conclusion¶

The computation of the evolved state with equations hung, even with a large decay.
This may be because of a bug.
Most of the time was spent with equality, but may be because of looping.
We will run again a simpler version and try to further diagnose.
