I'VE BEEN BATTLING WITH A PUZZLE IN WHICH, AFTER FINDING ONLY ONE "LOGIC ONLY PLACE" FOR A CERTAIN NUMBER, I HAVE NOT FOUND A SECOND ONE! THERE ARE TWO POSSIBILITIES: A) I MADE A MISTAKE IN THE ASSUMPTIONS PENCILED.... B) THIS IS MY FIRST PUZZLE WHERE YOU'LL HAVE TO TRY WHAT YOU JUST DESCRIBED AS A T&E WITH ONE OF TWO OPTIONS... AND GO ALL THE WAY TILL YOU EITHER SOLVE PUZZLE... OR FIND ALL OTHER PATHS AS "IMPOSSIBLE or ILLOGICAL".

(OR MAYBE I HAVEN'T SEEN THE CORRECT WAY AND THERE IS A THIRD ALTERNATIVE?). FOR ILLUSTRATION, THE PUZZLE

WITHOUT THE "ONLY ONE NUMBER I FOUND A PLACE FOR"..MCC wrote:My brain has gone on holiday and has taken a passport so it my be away for some time.

But in the meantime, using what's left.

Choosing a candidate from a bifurcate (or multifurcate?) position that leads to a solution, is a guess, with the proviso that the solver stops looking for another solution.

If the solver undertakes to look at the other candidate/s and their pathway/s and so therefore prove that the original choice was the only and therefore logical choice to make, then it can be called T&E.

It is also T&E if there are multiple solutions, so long, as ALL pathways are checked.

Just a thought.

If ALL pathways are not checked is it still a guess :?:

WILL SEE IF YOU ARE AWAKE SOON... OR IF ANYBODY ELSE WANTS TO SOLVE IT AND FIND A LOGICAL PATH OVERSEEN AT THE MOMENT... CHAU!
