None that I know of.

However, if you download my AI patcher (see sig), you can use it to adapt other AIs for P&N v2.

Just copy the AI into P&N, and follow the instructions included in the ZIP.

You must change the default "Engine Factor" in the patcher to a value greater than 42. 45 is now reccommended.
If you don't some AI designs may cause RangeCheckErrors.

Once you have used the patcher, the AI will be, not optimized, but useful in P&N v2.

I don't consider any of the AIs to be "optimized" for P&Nv2.
To be optimized, the AI would have to be tweaked to produce more refining worlds, and the research priorities would be changed a bit.
An optimized AI would be set up to use the advanced armor available, and would probably include Heavy Shield generators in its designs.

The AIs currently available for P&N v2 are reasonably good at at early tech levels, and I reccommend the highest tech costs with a low tech start.

Playing against other humans would be the best way to play, of course.
