Term Rewriting System R:
[x, y, z]
implies(not(x), y) -> or(x, y)
implies(not(x), or(y, z)) -> implies(y, or(x, z))
implies(x, or(y, z)) -> or(y, implies(x, z))

Innermost Termination of R to be shown. 



   R
     ↳Removing Redundant Rules



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

implies(not(x), y) -> or(x, y)
implies(not(x), or(y, z)) -> implies(y, or(x, z))

where the Polynomial interpretation:
  POL(implies(x1, x2))=  x1 + x2  
  POL(or(x1, x2))=  x1 + x2  
  POL(not(x1))=  1 + x1  
was used.

Not all Rules of R can be deleted, so we still have to regard a part of R.

         ↳Removing Redundant Rules



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

implies(x, or(y, z)) -> or(y, implies(x, z))

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

All Rules of R can be deleted.

R contains no Dependency Pairs and therefore no SCCs.
