Propositiones ad Acuendos Juvenes/Problems/18 - De Lupo et Capra et Fasciculo Cauli/Solution 2

Solution
The constraints here are that:


 * $(1): \quad$ The wolf, if left alone with the goat, would eat it, so these two may not be left alone together.
 * $(2): \quad$ The goat, if left alone with the bunch of cabbages, would eat it, so these two may not be left alone together.

Let $M$, $W$, $G$ and $C$ denote the man, wolf, goat and cabbages respectively.

Let them be crossing from $A$ to $B$.

As follows:


 * $M$ takes $G$ from $A$ to $B$.
 * $M$ returns to $A$.
 * $M$ takes $C$ from $A$ to $B$.
 * $M$ returns to $A$ with $G$.
 * $M$ takes $W$ from $A$ to $B$.
 * $M$ returns to $A$.
 * $M$ takes $G$ from $A$ to $B$.
