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(x2, x3, x4)
BUSY(x1, x2, x3, x4, x5, x6, x7) = x7
or(x1, x2) = or(x1, x2)

(11) QDPOrderProof (EQUIVALENT transformation)

We use the reduction pair processor [LPAR04].

The following pairs can be oriented strictly and are deleted.

BUSY(F, d, stop, b1, true, b3, i) → IDLE(F, open, stop, b1, false, 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) = x5
empty = empty
BUSY(x1, x2, x3, x4, x5, x6, x7) = x5
B = B
open = open
stop = stop
false = false
closed = closed
F = F
S = S
true = true
down = down
up = up
BF = BF
FS = FS

Recursive Path Order [RPO].
Precedence:

empty > false

open > false
stop > false
closed > false

true > false

We have to consider all minimal (P,Q,R)-chains.

(17) QDPOrderProof (EQUIVALENT transformation)

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

Recursive Path Order [RPO].
Precedence:

empty > closed
B > up > BF > closed
B > true > closed
open > closed
S > stop > F > BF > closed
S > stop > up > BF > closed
S > stop > true > closed
S > false > F > BF > closed
S > false > up > BF > closed
S > false > true > closed
S > false > FS > closed
S > down > F > BF > closed
S > down > true > closed
S > down > FS > closed

The following usable rules [FROCOS05] were oriented: none
