     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

IF(if(x, y, z), u, v) -> IF(x, if(y, u, v), if(z, u, v))
IF(if(x, y, z), u, v) -> IF(y, u, v)
IF(if(x, y, z), u, v) -> IF(z, u, v)

Furthermore, R contains one SCC.

     ↳DPs
       →DP Problem 1
         ↳Size-Change Principle


Dependency Pairs:

IF(if(x, y, z), u, v) -> IF(z, u, v)
IF(if(x, y, z), u, v) -> IF(y, u, v)
IF(if(x, y, z), u, v) -> IF(x, if(y, u, v), if(z, u, v))


Rule:


if(if(x, y, z), u, v) -> if(x, if(y, u, v), if(z, u, v))





We number the DPs as follows:
  1. IF(if(x, y, z), u, v) -> IF(z, u, v)
  2. IF(if(x, y, z), u, v) -> IF(y, u, v)
  3. IF(if(x, y, z), u, v) -> IF(x, if(y, u, v), if(z, u, v))
and get the following Size-Change Graph(s):
{3, 2, 1} , {3, 2, 1}
1>1
2=2
3=3
{3, 2, 1} , {3, 2, 1}
1>1

which lead(s) to this/these maximal multigraph(s):
{3, 2, 1} , {3, 2, 1}
1>1
{3, 2, 1} , {3, 2, 1}
1>1
2=2
3=3

DP: empty set
Oriented Rules: none

We used the order Homeomorphic Embedding Order with Non-Strict Precedence.
trivial


We obtain no new DP problems.
