My teacher gave me a riddle I couldn't figure out so I put digital monkeys at a typewriter until they did it for me. Press Space bar to toggle seeing the variables. I may have forgotten to add a way to track it's moves so I technically can't answer the riddle with this.. Also this DOES NOT find the best possible solution, just a solution. And the riddle was, (Not exactly the phrasing but it's still the same thing.) "A farmer needs to get all 4 of their products across a river, they have one canoe that can only support their weight an any ONE of their items. Their problem is that if they leave the Chicken alone with the Fox, the Fox will eat the Chicken, and if they leave the Chicken alone with the Grain, the Chicken will eat the Grain."
