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


The TRS R consists of the following rules:

-(x, 0) → x
-(s(x), s(y)) → -(x, y)
p(s(x)) → x
f(s(x), y) → f(p(-(s(x), y)), p(-(y, s(x))))
f(x, s(y)) → f(p(-(x, s(y))), p(-(s(y), x)))

(21) CdtRuleRemovalProof (UPPER BOUND(ADD(n^1)) transformation)

Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.

We considered the (Usable) Rules:

p(s(z0)) → z0
-(s(z0), s(z1)) → -(z0, z1)
-(z0, 0) → z0
And the Tuples:

F(s(z1), s(z0)) → c3(F(p(-(s(z1), s(z0))), p(-(z0, z1))), -'(s(z1), s(z0)), -'(s(z0), s(z1)))

The order we found is given by the following interpretation:
Polynomial interpretation :

POL(-(x1, x2)) = x1   
POL(-'(x1, x2)) = x1 + x2   
POL(0) = 0   
POL(F(x1, x2)) = x22 + x12   
POL(c1(x1)) = x1   
POL(c3(x1)) = x1   
POL(c3(x1, x2, x3)) = x1 + x2 + x3   
POL(c4(x1)) = x1   
POL(c4(x1, x2, x3)) = x1 + x2 + x3   
POL(p(x1)) = x1   
POL(s(x1)) = [2] + x1
