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

(0) Obligation:

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

if(if(x, y, z), u, v) → if(x, if(y, u, v), if(z, u, v))

Rewrite Strategy: INNERMOST

(1) CpxTrsToCdtProof (BOTH BOUNDS(ID, ID) transformation)

Converted CpxTRS to CDT

(2) Obligation:

Complexity Dependency Tuples Problem
Rules:

if(if(z0, z1, z2), z3, z4) → if(z0, if(z1, z3, z4), if(z2, z3, z4))

Tuples:

IF(if(z0, z1, z2), z3, z4) → c(IF(z0, if(z1, z3, z4), if(z2, z3, z4)), IF(z1, z3, z4), IF(z2, z3, z4))

S tuples:

IF(if(z0, z1, z2), z3, z4) → c(IF(z0, if(z1, z3, z4), if(z2, z3, z4)), IF(z1, z3, z4), IF(z2, z3, z4))

K tuples:none
Defined Rule Symbols:

(3) CdtUnreachableProof (EQUIVALENT transformation)

The following tuples could be removed as they are not reachable from basic start terms:

IF(if(z0, z1, z2), z3, z4) → c(IF(z0, if(z1, z3, z4), if(z2, z3, z4)), IF(z1, z3, z4), IF(z2, z3, z4))

(4) Obligation:

Complexity Dependency Tuples Problem
Rules:

if(if(z0, z1, z2), z3, z4) → if(z0, if(z1, z3, z4), if(z2, z3, z4))

Tuples:none
S tuples:none
K tuples:none
Defined Rule Symbols:

Defined Pair Symbols:none

Compound Symbols:none

(5) SIsEmptyProof (EQUIVALENT transformation)

The set S is empty
