Alternatively, you can remove the lines in Nemo/deps/build.jl that invoke
git. They aren't actually needed to run Nemo. They just download the source
code for the various modules, which are prebuilt anyway on Windows.

But I can't guarantee it'll work. We haven't worked on supporting rc0 yet.

It's because git has been removed on Windows in rc0. We don't support it
yet. You should be ok if you use Julia 0.4.6.

Hey,
  I am really interested in trying Nemo since I want to use the ArbFloats 
and ArbReals in DifferentialEquations.jl for "faster BigFloats". However, I 
am getting the following error when trying to build Nemo:

The use case is similar to AlphaGo, ie deterministic full information game with 
a huge state space.

That reinforcement package looks interesting, looking into it. Love to 
collaborate

Hi,

the way the type hierarchy has changed is only relevant if you have code
written against an old version of Nemo and want to switch it to the new
version. Probably the easiest way to see what's different is to look at
AbstractTypes.jl and compare with the older version you have.

We also changed the name of all the "generic" types in
generic/GenericTypes.jl, mainly by putting Gen in front of the type names.
Again you can compare with your older version of the file.

We do have complex root finding. The function is called roots. It is
documented on the polynomials page [1].

Bill.

Very cool! Is there a page where these changes are described more? How has 
the abstract type hierarchy been changed?

Also, I heard there was supposed to be a complex root isolation method?

What kind of reinforcement learning? If you're doing classical Q-learning 
for instance, a computer-algebra system will be of little help. You might 
be better off with the autodifferentiation packages.
