Re: [Sserver-three-d] a voice from china open competition: should we open our agent source in 3d simulation games

[Sander v. D. <sgv...@gm...>]

Hey all,

The more teams release their source code, the better. If champions do it,
they deserve a lot of respect, but in the end it is a team's own decision,
and there could be several reasons not to release your code, e.g. an
institution's intellectual property rules, or unpublished work contained in
the code.

To complement Klaus' email, there already is a list at [1] of libraries and
full agent source code releases.

You can also expect a new release of libbats after cleanup.

Cheers,
Sander
