Term Rewriting System R:
[x, y]
dfib(s(s(x)), y) -> dfib(s(x), dfib(x, y))

Innermost Termination of R to be shown.

     ↳Removing Redundant Rules



Removing the following rules from R which fullfill a polynomial ordering:

dfib(s(s(x)), y) -> dfib(s(x), dfib(x, y))

where the Polynomial interpretation:
  POL(dfib(x1, x2))=  x1 + x2  
  POL(s(x1))=  1 + 2·x1  
was used.

All Rules of R can be deleted.

R contains no Dependency Pairs and therefore no SCCs.
