In most of my solutions I have this motif:
|
v
(red) : Sync -> Start -> Sync ->
(blue) : Sync -> Sync -> Start ->
^
|
just to make sure that the blue Waldo runs first.
Except in the early research levels where counting steps is an option, I've always had to do something like this, up to 6 SYNCs at one point, which was not very pleasing!
What are more elegant options for synchronizing the Waldos?
