There are several difference in these domains.
-Size (the # of expansion)
-Branching factor (might be a factor of load balancing)
-Height-Width ratio (how accurate the h value is) -> can estimate with the descrepancy of initial h value and actual solution length
There are many sizes of sliding puzzles.
Might be able to find something useful for these puzzles.
3_6 (17) 3_7 (20) 3_8 (23) 4_4 (15) 4_5 (19) 4_6 (23) 5*5 (24)
