I found a blog post entitled “The Hardest Logic Puzzle Ever” and, naturally, it piqued my interest. The post points to a Wikipedia entry of the same name. Apparently, there is a puzzle commonly know as “The Hardest Logic Puzzle Ever” and it is attributed to Raymond Smullyan and John McCarthy.
It’s a kind of puzzle that most will be familiar with. The puzzler is presented with three gods. One that always lies, one that always tells the truth, and one that sometimes lies and sometimes tells the truth. Your task is to come up with three questions that will help you determine the identity of each god. The additional trick is that the gods speak their own language and you have to decipher that as well.
The solution to the puzzle is on the wikipedia page, so don’t read it all if you want to figure it out for yourself.
