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

### Specialization of cost equations f1/5 
* CE 4 is refined into CE [5] 
* CE 3 is refined into CE [6] 
* CE 2 is refined into CE [7] 


### Cost equations --> "Loop" of f1/5 
* CEs [6] --> Loop 5 
* CEs [7] --> Loop 6 
* CEs [5] --> Loop 7 

### Ranking functions of CR f1(A,B,C,D,E) 
* RF of phase [5]: [-A/2+B-3/2,B-1]

### Specialization of cost equations f0/5 
* CE 1 is refined into CE [8,9,10] 


### Cost equations --> "Loop" of f0/5 
* CEs [10] --> Loop 8

#### Cost of chains of f1(A,B,C,D,E):
* Chain [[6],7]: 1*it(6)+0
  Such that:it(6) =< A/2-B+1

  with precondition: [C=2,E=2,3>=A,A>=0,B>=0,A+1>=2*B] 

* Chain [[5],7]: 1*it(5)+0
  Such that:it(5) =< -A/2+B

  with precondition: [C=2,E=2,3>=B,A>=0,2*B>=A+4] 

* Chain [7]: 0
  with precondition: [C=2,E=2,3>=A,3>=B,A>=0,B>=0] 


#### Cost of chains of f0(A,B,C,D,E):
* Chain [10]: 0
  with precondition: [3>=A,3>=B,A>=0,B>=0] 

* Chain [9]: 1*s(1)+0
  Such that:s(1) =< A/2-B+1

  with precondition: [3>=A,A>=0,B>=0,A+1>=2*B] 

* Chain [8]: 1*s(2)+0
  Such that:s(2) =< -A/2+B

  with precondition: [3>=B,A>=0,2*B>=A+4]
