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:

   not(not(x)) -> x
   not(or(x, y)) -> and(not(x), not(y))
   not(and(x, y)) -> or(not(x), not(y))
   and(x, or(y, z)) -> or(and(x, y), and(x, z))
   and(or(y, z), x) -> or(and(x, y), and(x, z))

S is empty.
Rewrite Strategy: FULL
----------------------------------------

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

(2)
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:

   not(not(x)) -> x
   not(or(x, y)) -> and(not(x), not(y))
   not(and(x, y)) -> or(not(x), not(y))
   and(x, or(y, z)) -> or(and(x, y), and(x, z))
   and(or(y, z), x) -> or(and(x, y), and(x, z))

S is empty.
Rewrite Strategy: FULL
----------------------------------------

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

Obligation:
TRS:
Rules:
not(not(x)) -> x
not(or(x, y)) -> and(not(x), not(y))
not(and(x, y)) -> or(not(x), not(y))
and(x, or(y, z)) -> or(and(x, y), and(x, z))
and(or(y, z), x) -> or(and(x, y), and(x, z))

Types:
not :: or -> or
or :: or -> or -> or
and :: or -> or -> or
hole_or1_0 :: or
gen_or2_0 :: Nat -> or

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

(5) OrderProof (LOWER BOUND(ID))
Heuristically decided to analyse the following defined symbols:
not, and

They will be analysed ascendingly in the following order:
and < not

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

(6)
Obligation:
TRS:
Rules:
not(not(x)) -> x
not(or(x, y)) -> and(not(x), not(y))
not(and(x, y)) -> or(not(x), not(y))
and(x, or(y, z)) -> or(and(x, y), and(x, z))
and(or(y, z), x) -> or(and(x, y), and(x, z))

Types:
not :: or -> or
or :: or -> or -> or
and :: or -> or -> or
hole_or1_0 :: or
gen_or2_0 :: Nat -> or


Generator Equations:
gen_or2_0(0) <=> hole_or1_0
gen_or2_0(+(x, 1)) <=> or(hole_or1_0, gen_or2_0(x))


The following defined symbols remain to be analysed:
and, not

They will be analysed ascendingly in the following order:
and < not

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

(7) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:
not(gen_or2_0(+(1, n10828_0))) -> *3_0, rt in Omega(n10828_0)

Induction Base:
not(gen_or2_0(+(1, 0)))

Induction Step:
not(gen_or2_0(+(1, +(n10828_0, 1)))) ->_R^Omega(1)
and(not(hole_or1_0), not(gen_or2_0(+(1, n10828_0)))) ->_IH
and(not(hole_or1_0), *3_0)

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

Obligation:
Proved the lower bound n^1 for the following obligation:

TRS:

not(or(x, y)) -> and(not(x), not(y))
not(and(x, y)) -> or(not(x), not(y))
and(x, or(y, z)) -> or(and(x, y), and(x, z))
and(or(y, z), x) -> or(and(x, y), and(x, z))

Types:
not :: or -> or
or :: or -> or -> or
and :: or -> or -> or
hole_or1_0 :: or
gen_or2_0 :: Nat -> or


Generator Equations:
gen_or2_0(0) <=> hole_or1_0
gen_or2_0(+(x, 1)) <=> or(hole_or1_0, gen_or2_0(x))


The following defined symbols remain to be analysed:
