I'm dropping back in here again to support a suggestion SirkoZ has made:
The reason? Well, as I wrote already I am quite amazed by your pathfinder. You wrote in several places that you hope your algorithms are useful to others, and I indeed think so - I've been collecting ideas for an own AI for some time now, and I've noticed that that the rails your pathfinder builds are very much like what I'd like my AI to build. So I'd like to reuse this part (rail building) of your AI in my AI, whereas I plan to let my AI different "bigger picture" than your AI (more emphasis on networking than being most competitive).
I read the LICENSING file of GPLv3, and understand that of course I may reuse parts of your AI (that's the spirit of GPL after all) BUT, I must also license my work under the GPLv3 or later.
On the other hand, the OpenTTD devs have constructed a project site for AI authors including all sorts of useful tools that I would like to use. Unfortunately, the use of this service is limited for works licensed under the GPLv2
, which I cannot do if I use parts of your AI.
So, long story short, I would appreciate if you could make this possible somehow. I have heard about such things as licensing a work under both GPLv2 and GPLv3, so afaik it's possible - you may want to double check and/or ask someone more knowledgable about open source licenses than me though.
I'm looking forward to your answer
