[Retros] Two little SPG-challenges

[Nicolas.Dupont at math.univ-lille1.fr]

"Euclide" is clearly faster than "Natch" for that kind of problems :

>  - Pos B in 34min 04s)


Euclide, with a P4 3,4 GHz solves
- Pos A in 14 s
- Pos B in 24 s

Curiously, although I have almost the same computer as Anders, my version
of Natch takes around 4min for solving Pos A. Is it because I badly
parametrized  it ? If it is the case, how can I improve Natch's work ?
