Query: The Complexity of Robot Games on the Integer Line   In robot games on Z, two players add integers to a counter. Each player has a
finite set from which he picks the integer to add, and the objective of the
first player is to let the counter reach 0. We present an exponential-time
algorithm for deciding the winner of a robot game given the initial counter
value, and prove a matching lower bound.
