We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

SUBTRACT(List, cons(Head, Tail)) → SUBTRACT(delete(Head, List), Tail)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
SUBTRACT(x1, x2) = SUBTRACT(x1, x2)
cons(x1, x2) = cons(x2)
delete(x1, x2) = x2
nil = nil
case8(x1, x2, x3, x4) = x1
equal(x1, x2) = equal(x1, x2)

Lexicographic path order with status [19].
Precedence:

cons₁ > SUBTRACT₂
nil > SUBTRACT₂
equal₂ > SUBTRACT₂

Status:

SUBTRACT₂: [1,2]
nil: multiset
cons₁: multiset
equal₂: multiset

The following usable rules [14] were oriented:

delete(E, nil) → nil
delete(E, cons(Head, Tail)) → case8(Tail, Head, E, equal(E, Head))

The following pairs can be oriented strictly and are deleted.

APPEND(cons(Head, Tail), List) → APPEND(Tail, List)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
APPEND(x1, x2) = APPEND(x1)
cons(x1, x2) = cons(x1, x2)

Lexicographic path order with status [19].
Precedence:

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

LOCKER2_CHECK_AVAILABLES(cons(Resource, Resources), Locks) → LOCKER2_CHECK_AVAILABLES(Resources, Locks)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
LOCKER2_CHECK_AVAILABLES(x1, x2) = LOCKER2_CHECK_AVAILABLES(x1)
cons(x1, x2) = cons(x1, x2)

Lexicographic path order with status [19].
Precedence:

cons₂ > LOCKER2_{CHECK_{AVAILABLES₁}}

Status:

LOCKER2_{CHECK_{AVAILABLES₁}}: [1]
cons₂: multiset

The following usable rules [14] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

LOCKER2_MAP_CLAIM_LOCK(cons(Lock, Locks), Resources, Client) → LOCKER2_MAP_CLAIM_LOCK(Locks, Resources, Client)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
LOCKER2_MAP_CLAIM_LOCK(x1, x2, x3) = x1
cons(x1, x2) = cons(x1, x2)

Lexicographic path order with status [19].
Precedence:

trivial

Status:

cons₂: multiset

The following usable rules [14] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

RECORD_UPDATES(Record, Name, cons(tuple(Field, tuplenil(NewF)), Fields)) → RECORD_UPDATES(record_update(Record, Name, Field, NewF), Name, Fields)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
RECORD_UPDATES(x1, x2, x3) = x3
cons(x1, x2) = cons(x2)
tuple(x1, x2) = x1
tuplenil(x1) = tuplenil
record_update(x1, x2, x3, x4) = x4
mcrlrecord = mcrlrecord
lock = lock
pending = pending

Lexicographic path order with status [19].
Precedence:

tuplenil > lock
mcrlrecord > lock

Status:

tuplenil: []
lock: multiset
mcrlrecord: multiset
cons₁: multiset
pending: multiset

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

LOCKER2_MAP_PROMOTE_PENDING(cons(Lock, Locks), Pending) → LOCKER2_MAP_PROMOTE_PENDING(Locks, Pending)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
LOCKER2_MAP_PROMOTE_PENDING(x1, x2) = LOCKER2_MAP_PROMOTE_PENDING(x1)
cons(x1, x2) = cons(x1, x2)

Lexicographic path order with status [19].
Precedence:

cons₂ > LOCKER2_{MAP_{PROMOTE_PENDING₁}}

Status:

LOCKER2_{MAP_{PROMOTE_PENDING₁}}: [1]
cons₂: multiset

We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

ELEMENT(int(s(s(N1))), tuple(T1, T2)) → ELEMENT(int(s(N1)), T2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
ELEMENT(x1, x2) = ELEMENT(x1)
int(x1) = int(x1)
s(x1) = s(x1)
tuple(x1, x2) = tuple(x1, x2)

Lexicographic path order with status [19].
Precedence:

int₁ > ELEMENT₁
s₁ > ELEMENT₁

Status:

tuple₂: multiset
ELEMENT₁: [1]
s₁: [1]
int₁: [1]

The following usable rules [14] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

EQT(tuple(H1, T1), tuple(H2, T2)) → EQT(H1, H2)
EQT(cons(H1, T1), cons(H2, T2)) → EQT(T1, T2)
EQT(tuple(H1, T1), tuple(H2, T2)) → EQT(T1, T2)
EQT(cons(H1, T1), cons(H2, T2)) → EQT(H1, H2)

The remaining pairs can at least be oriented weakly.

EQT(tuplenil(H1), tuplenil(H2)) → EQT(H1, H2)
EQT(pid(N1), pid(N2)) → EQT(N1, N2)

Used ordering: Combined order from the following AFS and order.
EQT(x1, x2) = EQT(x1)
tuple(x1, x2) = tuple(x1, x2)
tuplenil(x1) = x1
pid(x1) = x1
cons(x1, x2) = cons(x1, x2)

Lexicographic path order with status [19].

Status:

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

EQT(tuplenil(H1), tuplenil(H2)) → EQT(H1, H2)

The remaining pairs can at least be oriented weakly.

EQT(pid(N1), pid(N2)) → EQT(N1, N2)

Used ordering: Combined order from the following AFS and order.
EQT(x1, x2) = EQT(x1)
pid(x1) = x1
tuplenil(x1) = tuplenil(x1)

Lexicographic path order with status [19].
Precedence:

trivial

Status:

tuplenil₁: multiset
EQT₁: [1]

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

EQT(pid(N1), pid(N2)) → EQT(N1, N2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
EQT(x1, x2) = EQT(x1)
pid(x1) = pid(x1)

Lexicographic path order with status [19].
Precedence:

pid₁ > EQT₁

Status:

EQT₁: [1]
pid₁: multiset

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

EQC(calls(E1, S1, CS1), calls(E2, S2, CS2)) → EQC(CS1, CS2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
EQC(x1, x2) = EQC(x1)
calls(x1, x2, x3) = calls(x1, x2, x3)

Lexicographic path order with status [19].
Precedence:

calls₃ > EQC₁

Status:

calls₃: multiset
EQC₁: [1]

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
