We use the reduction pair processor [LPAR04].


The following pairs can be oriented strictly and are deleted.

The remaining pairs can at least be oriented weakly.
Used ordering: Combined order from the following AFS and order.
IDLE(x1, x2, x3, x4, x5, x6, x7)  =  x7
newbuttons(x1, x2, x3, x4)  =  newbuttons(x3, x4)

We use the reduction pair processor [LPAR04].


The following pairs can be oriented strictly and are deleted.


BUSY(B, open, stop, false, b2, b3, i) → IDLE(B, closed, stop, false, b2, b3, i)
BUSY(F, open, stop, b1, false, b3, i) → IDLE(F, closed, stop, b1, false, b3, i)
BUSY(S, open, stop, b1, b2, false, i) → IDLE(S, closed, stop, b1, b2, false, i)
The remaining pairs can at least be oriented weakly.
Used ordering: Combined order from the following AFS and order.
IDLE(x1, x2, x3, x4, x5, x6, x7)  =  x2
empty  =  empty
BUSY(x1, x2, x3, x4, x5, x6, x7)  =  x2
B  =  B
open  =  open
stop  =  stop
false  =  false
closed  =  closed
F  =  F
S  =  S
down  =  down
up  =  up
true  =  true
BF  =  BF
FS  =  FS

Lexicographic path order with status [LPO].
