Question about swordfish

Postby Pascal_78630 » Tue Jun 26, 2018 9:28 am

Bonjour.
Dans le fichier joint, j'ai bien un swordfish avec le chiffre 9 (cases vertes).
Normalement je dois pouvoir ôter les candidats 9 des colonnes 4, 6 et 8.
Pourquoi ne puis-je pas enlever le candidat 9 de la case rose alors qu'il est situé dans la colonne 4 ?
Merci pour vos éclaircissements.
Bonne journée.
Pascal.

Bonsoir Pascal_78630,
J'imagine que le fichier joint était une image, Je ne suis pas expert de ces procédures, mais elle soit alors être entre les balises [ i m g ] [ / i m g ]

Un moyen simple pour vérifier est d'utiliser la case "preview"

There seems to be a problem uploading any files at the moment - see the other thread on this issue here. I've emailed Jason to look into it. Leren

La case rose appartient au swordfish, ceci est un swordfish "sec", il existe aussi bien en ligne qu'en colonne.

Code: Select all

The puzzle solved cell status has multiple solutions, which appears at the bottom of the image. Perhaps Champagne can translate this and get Pascal to submit the original puzzle. Otherwise it's difficult to provide help.

Bonjour Pascal,

Leren a bien noté le commentaire au bas de l'image :

grille invalide ; 100 solutions

Une grille invalide ne peut se résoudre par des règles logiques. Il faut rechercher les solutions en mode "essai erreur".

Note : pour ne pas perturber nos amis qui pratiquent tous l'Anglais, on peut passer par pm (ou par mail), mais on perdrait l'oeil de leren :roll:

Bonjour et merci à toutes et à tous pour votre aide.
Hello and thanks for your help.
Je vais me contenter des grilles sur ce site qui n'ont qu'une solution.
I'll settle for grids on this site that have only one solution.
A ce sujet, je viens de terminer la Historical Daily 50.
By the way, i just solved the Historical Daily 50.
Excellente journée à tous.
Great day for everyone.
Pascal.

Hello everybody.
Leren : I'm "working" the puzzles you let me.
In the first puzzle, I have a swordfish with the number 1 in the compartments in red and I can't take off the candidate number 1 of the compartment in pink.
Why ? I don't understand the swordfish !!! :(
Thanks a lot.

As an aid to help you understand why the different rules work, try to see what would happen if the eliminated digit was true.

In the grid you show it is possible for (1)r4c2 to be true with (1)r3c5, (1)r9c6 and (1)r8c2 so the the elimination cannot be proved from the coloured cells.
In short there are 3 rows needing (1) and four columns that can supply them so there is no Swordfish.

However look at the (4)s in r246. These three rows must all hold 4 but these can only come from 3 columns c235.
If one of the (4)s in any of the other cells in these columns was true, there would still be three rows needing a (4) but only two columns left to supply them.

Was it you or the program that coloured those cells?
