## Some results for pb1 on domain "Shakey"
The problem 1 is not complex enough to have time comparison, but we can observe different strategies.

### IPP algorithm
```
time step    0: MOVE R2 R1
time step    1: PUSH BOX1 R1 R2

time step    4: GRAB SMALL4 R3 LEFT
                GRAB SMALL3 R3 RIGHT
time step    5: PUSH BOX1 R3 R2
time step    6: PUSH BOX1 R2 R1
time step    7: RELEASE SMALL3 R1 RIGHT
                RELEASE SMALL4 R1 LEFT
