The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(1, 1).


The TRS R consists of the following rules:

   app(nil, YS) -> YS
   app(cons(X), YS) -> cons(X)
   from(X) -> cons(X)
   zWadr(nil, YS) -> nil
   zWadr(XS, nil) -> nil
   zWadr(cons(X), cons(Y)) -> cons(app(Y, cons(X)))
   prefix(L) -> cons(nil)

S is empty.
Rewrite Strategy: INNERMOST
----------------------------------------

(1) NarrowingOnBasicTermsTerminatesProof (FINISHED)
Constant runtime complexity proven by termination of constructor-based narrowing.

The maximal most general narrowing sequences give rise to the following rewrite sequences:

prefix(x0) ->^* cons(nil)

zWadr(cons(x0), cons(cons(x1))) ->^* cons(cons(x1))

zWadr(cons(x0), cons(nil)) ->^* cons(cons(x0))

zWadr(x0, nil) ->^* nil

zWadr(nil, x0) ->^* nil

from(x0) ->^* cons(x0)

app(cons(x0), x1) ->^* cons(x0)
