Preprocessing Cost Relations
=====================================

#### Computed strongly connected components 
0. recursive  : [eval/3]
1. non_recursive  : [exit_location/1]
2. non_recursive  : [eval_loop_cont/2]
3. non_recursive  : [start/3]

#### Obtained direct recursion through partial evaluation 
0. SCC is partially evaluated into eval/3
1. SCC is completely evaluated into other SCCs
2. SCC is completely evaluated into other SCCs
3. SCC is partially evaluated into start/3

Control-Flow Refinement of Cost Relations
=====================================

### Specialization of cost equations eval/3 
* CE 4 is refined into CE [5] 
* CE 2 is refined into CE [6] 
* CE 3 is refined into CE [7] 


### Cost equations --> "Loop" of eval/3 
* CEs [6] --> Loop 5 
* CEs [7] --> Loop 6 
* CEs [5] --> Loop 7 

### Ranking functions of CR eval(A,B,C) 
* RF of phase [5,6]: [A+B-2]

#### Partial ranking functions of CR eval(A,B,C) 
* Partial RF of phase [5,6]:
  - RF of loop [5:1]:
    A-1
    A-B depends on loops [6:1] 
  - RF of loop [6:1]:
    -A+B depends on loops [5:1] 
    B-1


### Specialization of cost equations start/3 
* CE 1 is refined into CE [8,9] 


### Cost equations --> "Loop" of start/3 
* CEs [9] --> Loop 8 
* CEs [8] --> Loop 9 

### Ranking functions of CR start(A,B,C) 

#### Partial ranking functions of CR start(A,B,C)
