(0)
Obligation:
The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(n^1, n^1).


The TRS R consists of the following rules:

   cond(true, x, y) -> cond(and(gr(x, 0), gr(y, 0)), p(x), p(y))
   and(true, true) -> true
   and(x, false) -> false
   and(false, x) -> false
   gr(0, 0) -> false
   gr(0, x) -> false
   gr(s(x), 0) -> true
   gr(s(x), s(y)) -> gr(x, y)
   p(0) -> 0
   p(s(x)) -> x

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^1).


The TRS R consists of the following rules:

   cond(true, x, y) -> cond(and(gr(x, 0), gr(y, 0)), p(x), p(y)) [1]
   and(true, true) -> true [1]
   and(x, false) -> false [1]
   and(false, x) -> false [1]
   gr(0, 0) -> false [1]
   gr(0, x) -> false [1]
   gr(s(x), 0) -> true [1]
   gr(s(x), s(y)) -> gr(x, y) [1]
   p(0) -> 0 [1]
   p(s(x)) -> x [1]

Infered types.
----------------------------------------

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

   cond(true, x, y) -> cond(and(gr(x, 0), gr(y, 0)), p(x), p(y)) [1]
   and(true, true) -> true [1]
   and(x, false) -> false [1]

   gr(s(x), s(y)) -> gr(x, y) [1]
   p(0) -> 0 [1]

and :: true:false -> true:false -> true:false
gr :: 0:s -> 0:s -> true:false
0 :: 0:s
p :: 0:s -> 0:s
false :: true:false
s :: 0:s -> 0:s

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

(5) CompletionProof (UPPER BOUND(ID))
The transformation into a RNTS is sound, since:

(a) The obligation is a constructor system where every type has a constant constructor,

(b) The following defined symbols do not have to be completely defined, as they can never occur inside other defined symbols:

   cond_3

(c) The following functions are completely defined:

   and_2
   gr_2
   p_1

Due to the following rules being added:
none

And the following fresh constants:    const

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

(6)

Runtime Complexity Weighted TRS with Types.

   and(x, false) -> false [1]
   and(false, x) -> false [1]
   gr(0, 0) -> false [1]
   gr(0, x) -> false [1]
   gr(s(x), 0) -> true [1]
   gr(s(x), s(y)) -> gr(x, y) [1]
   p(0) -> 0 [1]
   p(s(x)) -> x [1]

The TRS has the following type information:
cond :: true:false -> 0:s -> 0:s -> cond
true :: true:false
and :: true:false -> true:false -> true:false
gr :: 0:s -> 0:s -> true:false
0 :: 0:s
p :: 0:s -> 0:s
false :: true:false
s :: 0:s -> 0:s
const :: cond

   cond(true, s(x'), s(x2)) -> cond(and(true, true), x', x2) [5]
   and(true, true) -> true [1]
   and(x, false) -> false [1]
   and(false, x) -> false [1]
   gr(0, 0) -> false [1]
   gr(0, x) -> false [1]
   gr(s(x), 0) -> true [1]
   gr(s(x), s(y)) -> gr(x, y) [1]
   p(0) -> 0 [1]
   p(s(x)) -> x [1]

The TRS has the following type information:

   0 => 0
   false => 0
   const => 0

Proved the following rewrite lemma:

Induction Base:
gr(gen_0':s4_0(0), gen_0':s4_0(0)) ->_R^Omega(1)
false

Induction Step:
gr(gen_0':s4_0(+(n6_0, 1)), gen_0':s4_0(+(n6_0, 1))) ->_R^Omega(1)
gr(gen_0':s4_0(n6_0), gen_0':s4_0(n6_0)) ->_IH
false

We have rt in Omega(n^1) and sz in O(n). Thus, we have irc_R in Omega(n).
