0.3.0

This release adds the Wolf, Goat and Cabbage problem to the application.

---

These two commands are equivalent:

cargo run -- wolf-goat-cabbage
cargo run -- wolf-goat-cabbage --boat 2 --farmers 1 --wolves 1 --goats 1 --cabbage 1

Running them prints a solution like the following:

  At t=0; left bank: farmer, wolf, goat and cabbage; right bank: empty
   → farmer and goat cross forward
  At t=1; left bank: wolf and cabbage; right bank: farmer and goat
   ← farmer returns alone
  At t=2; left bank: farmer, wolf and cabbage; right bank: goat
   → farmer and cabbage cross forward
  At t=3; left bank: wolf; right bank: farmer, goat and cabbage
   ← farmer and goat return
  At t=4; left bank: farmer, wolf and goat; right bank: cabbage
   → farmer and wolf cross forward
  At t=5; left bank: goat; right bank: farmer, wolf and cabbage
   ← farmer returns alone
  At t=6; left bank: farmer and goat; right bank: wolf and cabbage
   → farmer and goat cross forward
  At t=7; left bank: empty; right bank: farmer, wolf, goat and cabbage

0.2.0

This release adds the Bridge and Torch problem to the application.

---

These two commands are equivalent:

cargo run -- bridge-and-torch
cargo run -- bridge-and-torch --bridge 2 --torch 15 --person 1 --person 2 --person 5 --person 8

Running them prints a solution like the following:

  At 0 minutes: [<1>, <2>, <5>, <8>] on the left, nobody on the right (torch: 15 minutes)
   → [<1>, <2>] cross forward, taking 2 minutes
  At 2 minutes: [<5>, <8>] on the left, [<1>, <2>] on the right (torch: 13 minutes)
   ← [<1>] returns, taking 1 minute
  At 3 minutes: [<5>, <8>, <1>] on the left, [<2>] on the right (torch: 12 minutes)
   → [<5>, <8>] cross forward, taking 8 minutes
  At 11 minutes: [<1>] on the left, [<2>, <5>, <8>] on the right (torch: 4 minutes)
   ← [<2>] returns, taking 2 minutes
  At 13 minutes: [<1>, <2>] on the left, [<5>, <8>] on the right (torch: 2 minutes)
   → [<1>, <2>] cross forward, taking 2 minutes
  At 15 minutes: nobody on the left, [<5>, <8>, <1>, <2>] on the right (torch: 0 minutes)

0.1.0

The initial release with the original problem in a minimalist-ish form.
