Strategy AI and choke points

I finally started working with the strategy map AI. I want the AI to be smart so it can match the human player on harder difficulty levels. So I think it is important that the AI can for example use the surroundings to its advantage. So I made an algorithm which detects these choke points on the map. This knowledge can be used when the AI decides which star systems to colonize so that it can then defend its area effectively by building static defences and focusing its ships on the choke points. Also, because the process looks cool it makes a nice video. 🙂
