En réponse à Anne pour le #11 voici comment j'ai procédé : je trace tous les chemins possibles sans placer les marques, si possible avec des couleurs différentes pour bien les distinguer. Puis je marque toutes les intersections de ces différents chemins deux à deux. C'est a priori sur ces intersections qu'il va falloir placer les trois marques pour rabouter entre eux les chemins les plus longs. Bien sûr on regarde prioritairement les chemins les plus longs et on constate que les intersections se situent fréquemment vers le milieu, ce qui ne sera pas très intéressant car il faudra choisir une direction et l'on aura donc perdu la moitié de la longueur environ. Mais en y regardant de plus près on constate que deux des grandes chaînes possèdent une intersection quasiment à une de leur extrémité. Il n'y a alors plus qu'à regarder si les chemins qui en sont issus se recoupent, ce qui se vérifie et permet donc de positionner les trois marques . . .

Thanks Riad for this wonderful contest. I had a lot of fun as usual.
Could you please check something. I think I also have the max score of 99 points. In puzzle 10 I had 105 names and 561 letters, but I received no points.
