Term Rewriting System R:
[x, y, z]
.(.(x, y), z) -> .(x, .(y, z))
Innermost Termination of R to be shown.
R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
.'(.(x, y), z) -> .'(x, .(y, z))
.'(.(x, y), z) -> .'(y, z)
Furthermore, R contains one SCC.
R
↳DPs
→DP Problem 1
↳Forward Instantiation Transformation
Dependency Pair:
.'(.(x, y), z) -> .'(y, z)
Rule:
.(.(x, y), z) -> .(x, .(y, z))
Strategy:
innermost
On this DP problem, a Forward Instantiation SCC transformation can be performed.
As a result of transforming the rule
.'(.(x, y), z) -> .'(y, z)
one new Dependency Pair
is created:
.'(.(x, .(x'', y'')), z'') -> .'(.(x'', y''), z'')
The transformation is resulting in one new DP problem:
R
↳DPs
→DP Problem 1
↳FwdInst
→DP Problem 2
↳Remaining Obligation(s)
The following remains to be proven:
Dependency Pair:
.'(.(x, .(x'', y'')), z'') -> .'(.(x'', y''), z'')
Rule:
.(.(x, y), z) -> .(x, .(y, z))
Strategy:
innermost
Innermost Termination of R could not be shown.
