----------------------------------------

(0)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   minus(0, y) -> 0
   minus(s(x), y) -> if(gt(s(x), y), x, y)
   if(true, x, y) -> s(minus(x, y))
   if(false, x, y) -> 0
   mod(x, 0) -> 0
   mod(x, s(y)) -> if1(lt(x, s(y)), x, s(y))
   if1(true, x, y) -> x
   if1(false, x, y) -> mod(minus(x, y), y)
   gt(0, y) -> false
   gt(s(x), 0) -> true
   gt(s(x), s(y)) -> gt(x, y)
   lt(x, 0) -> false
   lt(0, s(x)) -> true
   lt(s(x), s(y)) -> lt(x, y)

Q is empty.

----------------------------------------

(1) Overlay + Local Confluence (EQUIVALENT)
The TRS is overlay and locally confluent. By [NOC] we can switch to innermost.
