It often happens that an end game is reached where both opponents are confined
in a space, isolated from the opponent. At this point the optimal strategy becomes
filling the space as densely as possible, hoping for the other opponent to crash
sooner. Any good Tron player should master this technique. The game depicted
on fig. 3.36 shows human and agent in a match of endurance.
Figure 3.36:
Space Filling. R. 5470006 and
Human 5074 engage in a space-filling endurance contest. The difference between
their perceptual modes is visible: The human is allowed tighter turns, yet its
finger ability is limited. The agent cannot measure with precision the space
remaining, so sometimes recurs to spiraling in, then out as in the upper right
region. In the end the human fails to enter a narrow passage and loses (black=agent,
gray=human).
