Another post from way back when. This one has a math puzzle that is as good today as it was the day it was created. The puzzle is courtesy Amit Chakrabarti, Professor of Computer Science at Dartmouth, who was my co-blogger on Zoo Station.

[From AC] A nice puzzle from Amit for the Friday evening :

You are travelling to a city in a remote and unknown land and you come to a fork in the road and don't know which branch (left or right) to take. You meet three locals, who know each other. One of them always tells the truth, one always lies and the third answers at random. You yourself know all of this (somehow) but you don't know which person is which.

By asking two yes/no questions, each addressed to a single person, determine the way to the city.

Have a go at it while it is still fresh.😀

Hi, thanks for stopping by!

My name is Anand. Thanks for stopping by my blog! I created this blog for myself, my family and denizens of the Internet that may want to know more about my writing work. If you are looking for my Professional C.V., please click here.

I am a computer engineer by way of undergraduate and graduate education. I am a technologist, author and entrepreneur by profession. I have also worked in research in computer science, strategic management and Indology.

Here's something cool! Take a look at the pictures above. The images above were created with the help of Voila, an A.I. artist. The first picture is an actual picture of me from 2021. The second and third pictures were rendered by Voila as 15th and 18th century artists' versions of the first picture. If Leonardo Da Vinci or William Blake had been alive today, this is how they would have rendered us. Hope you liked that bit of A.I. magic!
