The Runtime Complexity (full) of the given CpxTRS could be proven to be BOUNDS(n^1, INF).


The TRS R consists of the following rules:

   min(x, 0) -> 0
   min(0, y) -> 0
   min(s(x), s(y)) -> s(min(x, y))
   max(x, 0) -> x
   max(0, y) -> y
   max(s(x), s(y)) -> s(max(x, y))
   -(x, 0) -> x
   -(s(x), s(y)) -> -(x, y)
   gcd(s(x), 0) -> s(x)
   gcd(0, s(x)) -> s(x)
   gcd(s(x), s(y)) -> gcd(-(max(x, y), min(x, y)), s(min(x, y)))

S is empty.

(1) RenamingProof (BOTH BOUNDS(ID, ID))
Renamed function symbols to avoid clashes with predefined symbol.

Obligation:
The Runtime Complexity (full) of the given CpxTRS could be proven to be BOUNDS(n^1, INF).


The TRS R consists of the following rules:

   min(x, 0') -> 0'
   min(0', y) -> 0'
   min(s(x), s(y)) -> s(min(x, y))
   max(x, 0') -> x
   max(0', y) -> y
   max(s(x), s(y)) -> s(max(x, y))
   -(x, 0') -> x
   -(s(x), s(y)) -> -(x, y)
   gcd(s(x), 0') -> s(x)
   gcd(0', s(x)) -> s(x)
   gcd(s(x), s(y)) -> gcd(-(max(x, y), min(x, y)), s(min(x, y)))

S is empty.
