I know of no applications, nevertheless it seems that there should be some applications for clever search outside formal games. Military applications come to mind. Here is a simple cartoon of a potential application. Imagine two ships with one trying to traverse an area filled with islands of different shape. The second ship is trying to intercept the first. Both ships are under satellite surveillance and know each other's positions at all times. The choice of right or left around an island is analogous to a chess "move". Tactics abound: for example, if the ships are on opposite sides of an island they are in Zugzwang. If the interceptor goes right, the aggressor can also go right avoiding the defender, etc., etc. Such tactics can and should be foreseen many turns (pun intended) in advance. Hence the applicability of search. Perhaps some time I will think about applications seriously and write a proposal... Cheers, Walter
