(7) QDPOrderProof (EQUIVALENT transformation)

We use the reduction pair processor [LPAR04].

The following pairs can be oriented strictly and are deleted.

IDLE(fl, d, m, b1, b2, b3, newbuttons(i1, i2, i3, i)) → BUSY(fl, d, m, or(b1, i1), or(b2, i2), or(b3, i3), 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)  =  x7
newbuttons(x1, x2, x3, x4)  =  newbuttons(x4)
BUSY(x1, x2, x3, x4, x5, x6, x7)  =  x7
or(x1, x2)  =  or(x2)
B  =  B
closed  =  closed
stop  =  stop
false  =  false
F  =  F
S  =  S
open  =  open
empty  =  empty

(13) QDPOrderProof (EQUIVALENT transformation)

We use the reduction pair processor [LPAR04].

The following pairs can be oriented strictly and are deleted.

BUSY(B, d, stop, true, b2, b3, i) → IDLE(B, open, stop, false, b2, b3, 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)  =  x4
empty  =  empty
BUSY(x1, x2, x3, x4, x5, x6, x7)  =  x4
B  =  B
open  =  open
stop  =  stop
false  =  false
closed  =  closed
F  =  F
S  =  S
true  =  true
down  =  down
