Input (COPS 1285)
We consider the TRS containing the following rules:
a(b(a(x))) |
→ |
b(a(b(x))) |
(1) |
b(a(b(x))) |
→ |
a(b(a(x))) |
(2) |
p |
→ |
a(p) |
(3) |
p |
→ |
b(p) |
(4) |
The underlying signature is as follows:
{a/1, b/1, p/0}Property / Task
Prove or disprove confluence.Answer / Result
Yes.Proof (by csi @ CoCo 2022)
1 Redundant Rules Transformation
To prove that the TRS is (non-)confluent, we show (non-)confluence of the following
modified system:
p |
→ |
b(p) |
(4) |
p |
→ |
a(p) |
(3) |
b(a(b(x))) |
→ |
a(b(a(x))) |
(2) |
a(b(a(x))) |
→ |
b(a(b(x))) |
(1) |
p |
→ |
b(b(p)) |
(5) |
p |
→ |
b(a(p)) |
(6) |
p |
→ |
a(b(p)) |
(7) |
p |
→ |
a(a(p)) |
(8) |
b(a(b(x))) |
→ |
b(a(b(x))) |
(9) |
a(b(a(x))) |
→ |
a(b(a(x))) |
(10) |
All redundant rules that were added or removed can be
simulated in 2 steps
.
1.1 Decreasing Diagrams
1.1.2 Rule Labeling
Confluence is proven, because all critical peaks can be joined decreasingly
using the following rule labeling function (rules that are not shown have label 0).

The critical pairs can be joined as follows. Here,
↔ is always chosen as an appropriate rewrite relation which
is automatically inferred by the certifier.
