Ah, this answers my question on the other branch of this thread. It does count if the person crosses. It is solvable, the trick is at least one of the times you have to send 2 people back across the river. Here's my solution (C for cannibal, M for missionary). The parens show the change in people distribution in the form of orginal_shore,new_shore with => to show transitions.

1. C and M row across, the M rows back (CCCMMM,none => CCMM,CM => CCMMM,C)
2. Two C row across, one C rows back (CCMMM,C => MMM,CCC => CMMM,CC)
3. Two M row across, one C and one M row back (CMMM,CC => CM,CCMM => CCMM,CM)
4. Two M row across, the C rows back (CCMM,CM => CC,CMMM => CCC,MMM)
5. Two C row across, one C rows back (CCC,MMM => C,CCMMM => CC,CMMM)
6. The remaining two C row across

Okay, now I can get back to work without this bugging me.
