f(g(f(a), h(a, f(a)))) -> f(h(g(f(a), a), g(f(a), f(a))))
Termination of R to be shown.
R
↳Removing Redundant Rules
Removing the following rules from R which fullfill a polynomial ordering:
f(g(f(a), h(a, f(a)))) -> f(h(g(f(a), a), g(f(a), f(a))))
where the Polynomial interpretation:
POL(g(x1, x2)) | = x1 + 2·x2 |
POL(h(x1, x2)) | = 1 + x1 + x2 |
POL(a) | = 0 |
POL(f(x1)) | = x1 |
was used.
All Rules of R can be deleted.

↳Overlay and local confluence Check
The TRS is overlay and locally confluent (all critical pairs are trivially joinable).Hence, we can switch to innermost.

↳Dependency Pair Analysis
R contains no Dependency Pairs and therefore no SCCs.
