Runtime Complexity TRS:
The TRS R consists of the following rules:

:(:(x, y), z) → :(x, :(y, z))
:(+(x, y), z) → +(:(x, z), :(y, z))
:(z, +(x, f(y))) → :(g(z, y), +(x, a))

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

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

:'(:(z0, z1), z2) → c(:'(z0, :(z1, z2)), :'(z1, z2))
:'(+(z0, z1), z2) → c1(:'(z0, z2), :'(z1, z2))
We considered the (Usable) Rules:none
And the Tuples:

:'(:(z0, z1), z2) → c(:'(z0, :(z1, z2)), :'(z1, z2))
:'(+(z0, z1), z2) → c1(:'(z0, z2), :'(z1, z2))
The order we found is given by the following interpretation:
Polynomial interpretation :

POL(+(x1, x2)) = [4] + x1 + x2   
POL(:(x1, x2)) = [4] + x1 + [2]x2   
POL(:'(x1, x2)) = [2]x1   
POL(a) = [3]   
POL(c(x1, x2)) = x1 + x2   
POL(c1(x1, x2)) = x1 + x2   
POL(f(x1)) = [4]   
POL(g(x1, x2)) = [5]
