Adaptive search space pruning in complex strategic problems
Fig 2
Participants search size does not depend on the board’s complexity.
A) Participants’ search size (blue) is small and fixed compared with the search size of alpha-beta pruning (gray). B) The percent of participants who solved correctly each of the board configurations, by board complexity. As board complexity increases, participants’ success rate decreases, yet at a slower rate compared to the board’s complexity increase. Error bars depict 95% confidence intervals.
