missionaries and cannibals problem

in studies of problem solving, a task proposing that three missionaries and three cannibals are on one side of a river and must cross to the other side in a canoe that will only hold two people. The missionaries on either bank must never be outnumbered by the cannibals or they will be eaten, and the canoe must have at least one passenger each time it crosses the river. The solver must plan a series of moves that will get the group across the river in a way that meets these constraints.
