   F(z, z') -{ 1 }-> 1 + F(1 + (1 + z), z' - 2) :|: z' - 2 >= 0, z >= 0

Function symbols to be analyzed: {F}
Previous analysis results are:
  F: runtime: INF, size: O(1) [0]

(51) CompletionProof (UPPER BOUND(ID))
The TRS is a completely defined constructor system, as every type has a constant constructor and the following rules were added:

   F(v0, v1) -> null_F [0]

And the following fresh constants:    null_F, const

Runtime Complexity Weighted TRS where all functions are completely defined. The underlying TRS is:

Runtime Complexity Weighted TRS with Types.
The TRS R consists of the following rules:

   F(z0, a(b(z1))) -> c1(F(a(b(z0)), z1)) [1]
   F(z0, b(c(z1))) -> c2(F(b(c(z0)), z1)) [1]
   F(z0, c(a(z1))) -> c3(F(c(a(z0)), z1)) [1]
   F(a(z0), z1) -> c4(F(z0, a(z1))) [1]
   F(b(z0), z1) -> c5(F(z0, b(z1))) [1]
   F(c(z0), z1) -> c6(F(z0, c(z1))) [1]
   F(v0, v1) -> null_F [0]

The TRS has the following type information:
F :: b:a:c -> b:a:c -> c1:c2:c3:c4:c5:c6:null_F
a :: b:a:c -> b:a:c
b :: b:a:c -> b:a:c
c1 :: c1:c2:c3:c4:c5:c6:null_F -> c1:c2:c3:c4:c5:c6:null_F
c :: b:a:c -> b:a:c
c2 :: c1:c2:c3:c4:c5:c6:null_F -> c1:c2:c3:c4:c5:c6:null_F
c3 :: c1:c2:c3:c4:c5:c6:null_F -> c1:c2:c3:c4:c5:c6:null_F
c4 :: c1:c2:c3:c4:c5:c6:null_F -> c1:c2:c3:c4:c5:c6:null_F
c5 :: c1:c2:c3:c4:c5:c6:null_F -> c1:c2:c3:c4:c5:c6:null_F
c6 :: c1:c2:c3:c4:c5:c6:null_F -> c1:c2:c3:c4:c5:c6:null_F
null_F :: c1:c2:c3:c4:c5:c6:null_F
const :: b:a:c

(53) CpxTypedWeightedTrsToRntsProof (UPPER BOUND(ID))
Transformed the TRS into an over-approximating RNTS by (improved) Size Abstraction.
The constant constructors are abstracted as follows:

   null_F => 0
   const => 0

Only complete derivations are relevant for the runtime complexity.
