If this asymmetry really bothers you, you could very easily fix this by
wrapping the search around. There's no asymmetry in a circle.
That doesn't fix anything.
Why not? The whole argument is about a bias against points towards the end.
In a circular list there is no 'end'.
No, it was a bias towards moves "behind" illegal moves.
Those moves are twice as likely to be played than other moves.
Consider a list with 5 moves:
[Move1] [Move2] [Move3] [Move4] [Move5]
You create a random number between 1 and 5. If Move2 is illegeal
for example, then you will play
Move1 if random#=1
Move3 if random#=2 or 3,
Move4 =4
Move5 =5
Move3 is twice as likely to be played. Even if you make a circular
list.
