Humm possible, mais il faut imposer à la somme des variables d'être 
minimale. Quoique je me demande si les contraintes de régions (chiffres 
tous différents compris entre 1 et taille-région) + les contraintes de 
distances >=1 entre nombres adjacents me semble automatiquement tout 
"caler" sur des entiers.

On doit pouvoir jouer avec solveurs QCP 
(https://en.wikipedia.org/wiki/Quadratically_constrained_quadratic_program), 
mais beaucoup sont payants :( Mais probablement que les "academics" y 
ont droit sans frais.
