Conclusion

The proposed conformation organization has a dual purpose. Firstly, it provides a tool for validating a program. This is what we might call an evaluation mode. But it may also enable us to move on to a more dynamic process, that of design. In this situation, the aim is to participate in setting the program. In fact, both situations depend on the engine used.

To fully understand what distinguishes these two states, we need to return to the expectations that motivate the use of each of them:

• evaluation relates to a hypothesis, the aim of which is to check whether it can lead to a satisfactory result. The aim is not to find the solution, but to determine whether an acceptable solution is possible;

• design, on the other hand, is a process of finding the best solution to an objective considered...
