(0)
Obligation:
The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(n^2, n^2).


The TRS R consists of the following rules:

   nonZero(0) -> false
   nonZero(s(x)) -> true
   p(s(0)) -> 0
   p(s(s(x))) -> s(p(s(x)))
   id_inc(x) -> x
   id_inc(x) -> s(x)
   random(x) -> rand(x, 0)
   rand(x, y) -> if(nonZero(x), x, y)
   if(false, x, y) -> y
   if(true, x, y) -> rand(p(x), id_inc(y))

S is empty.
Rewrite Strategy: INNERMOST

(1) RelTrsToWeightedTrsProof (BOTH BOUNDS(ID, ID))
Transformed relative TRS to weighted TRS
----------------------------------------

(2)
Obligation:
The Runtime Complexity (innermost) of the given CpxWeightedTrs could be proven to be BOUNDS(1, n^2).


The TRS R consists of the following rules:

   nonZero(0) -> false [1]
   nonZero(s(x)) -> true [1]
   p(s(0)) -> 0 [1]
   p(s(s(x))) -> s(p(s(x))) [1]
   id_inc(x) -> x [1]
   id_inc(x) -> s(x) [1]
   random(x) -> rand(x, 0) [1]
   rand(x, y) -> if(nonZero(x), x, y) [1]
   if(false, x, y) -> y [1]
   if(true, x, y) -> rand(p(x), id_inc(y)) [1]

Rewrite Strategy: INNERMOST
----------------------------------------

(3) TypeInferenceProof (BOTH BOUNDS(ID, ID))
Infered types.
----------------------------------------

(4)
Obligation:
Runtime Complexity Weighted TRS with Types.
The TRS R consists of the following rules:

   nonZero(0) -> false [1]
   nonZero(s(x)) -> true [1]
   p(s(0)) -> 0 [1]
   p(s(s(x))) -> s(p(s(x))) [1]
   id_inc(x) -> x [1]
   id_inc(x) -> s(x) [1]
