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) = x2
cons(x1, x2) = cons(x2)
delete(x1, x2) = delete
nil = nil
case8(x1, x2, x3, x4) = case8(x1, x2, x3, x4)
equal(x1, x2) = equal

Recursive path order with status [2].
Quasi-Precedence:

cons₁ > [delete, case8₄, equal]
nil > [delete, case8₄, equal]

Status:

case8₄: multiset
delete: []
equal: []
cons₁: multiset
nil: multiset

The following usable rules [14] were oriented: none

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, x2)
cons(x1, x2) = cons(x1, x2)

Recursive path order with status [2].
Quasi-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, x2)
cons(x1, x2) = cons(x1, x2)

Recursive path order with status [2].
Quasi-Precedence:

trivial

Status:

LOCKER2_{CHECK_{AVAILABLES₂}}: multiset
cons₂: 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.

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) = LOCKER2_MAP_CLAIM_LOCK(x1, x2, x3)
cons(x1, x2) = cons(x1, x2)

Recursive path order with status [2].
Quasi-Precedence:

[LOCKER2_{MAP_{CLAIM_LOCK₃}}, cons_2]

Status:

LOCKER2_{MAP_{CLAIM_LOCK₃}}: multiset
cons₂: multiset

The following usable rules [14] were oriented: none

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) = tuple(x1, x2)
tuplenil(x1) = tuplenil
record_update(x1, x2, x3, x4) = record_update(x4)
mcrlrecord = mcrlrecord
lock = lock
pending = pending

Recursive path order with status [2].
Quasi-Precedence:

[tuplenil, mcrlrecord] > [cons₁, tuple₂, record_update₁, lock]
pending > [cons₁, tuple₂, record_update₁, lock]

Status:

record_update₁: multiset
tuplenil: []
tuple₂: multiset
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, x2)
cons(x1, x2) = cons(x1, x2)

Recursive path order with status [2].
Quasi-Precedence:

trivial

Status:

LOCKER2_{MAP_{PROMOTE_PENDING₂}}: multiset
cons₂: multiset

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.

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) = x1
s(x1) = s(x1)
tuple(x1, x2) = tuple(x2)

Recursive path order with status [2].
Quasi-Precedence:

tuple₁ > s₁ > ELEMENT₁

Status:

ELEMENT₁: multiset

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) = x2
tuple(x1, x2) = tuple(x1, x2)
tuplenil(x1) = x1
pid(x1) = x1
cons(x1, x2) = cons(x1, x2)

Recursive path order with status [2].
Quasi-Precedence:

trivial

Status:

tuple₂: [1,2]
cons₂: multiset

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.

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

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

Recursive path order with status [2].
Quasi-Precedence:

[EQT₁, pid_1]

Status:

EQT₁: multiset
pid₁: multiset

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.
none
Used ordering: Combined order from the following AFS and order.
EQT(x1, x2) = EQT(x1)
tuplenil(x1) = tuplenil(x1)

Recursive path order with status [2].
Quasi-Precedence:

[EQT₁, tuplenil_1]

Status:

tuplenil₁: multiset
EQT₁: multiset

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

Recursive path order with status [2].
Quasi-Precedence:

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(x3)

Recursive path order with status [2].
Quasi-Precedence:

trivial

Status:

calls₁: multiset
EQC₁: 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.
