TruthLens AI Summary

The article presents two intriguing puzzles designed to challenge problem-solving skills and logical reasoning. The first puzzle involves a scenario where a dealer has placed one hundred cards numbered from 1 to 100 face down on a table. The objective is to identify the cards representing the numbers one and one hundred without flipping them over. Participants can only gain information about the cards through comparisons, asking the dealer which of any two selected cards is smaller or larger. The solution requires a systematic approach, where by making a series of 99 comparisons, one can deduce which card is the lowest and which is the highest. This method emphasizes strategic thinking, as it allows the solver to efficiently determine both the lowest and highest cards with a total of 198 comparisons. The challenge lies in finding a more optimal strategy to achieve this task with fewer comparisons, which adds an additional layer of complexity to the puzzle.

The second puzzle, referred to as 'The rope trick,' places the solver in a hypothetical situation where they are a burglar on top of a 20-meter building. The building features a ledge halfway down, and the burglar has access to a 15-meter length of rope and a knife. The goal is to safely descend the building using the rope without jumping off or using it in a straightforward manner. The puzzle allows for creative applications of knots and cutting the rope, leading to various potential solutions. It encourages the solver to think innovatively about how to utilize the available resources to ensure a safe descent. The puzzles are presented by Geza Bohus, a former maths olympiad contestant with a background in machine learning and financial modeling, and he invites readers to discuss their favorite knot techniques while engaging with these challenges.

Unanalyzed Article Content

Two very different puzzles today. In the first, you have to identify two numbers. In the second, you have to escape off a roof.

  1. Go compare!

A dealer places one hundred cards on a table. On their face-down sides are the numbers from 1 to 100. The cards are randomly arranged so you have no idea at the beginning which card is which. Your task is to identify the 1 card and the 100 cardwithoutturning any of them over.

The only way to learn information about the cards is by comparison. At any stage, you may choose two and ask the dealer which is smaller and which is larger. The dealer always knows. They will never tell you the number on the cards, just which is smaller and which is larger.

It is possible to identify the 1 card after asking the dealer to make 99 comparisons. First, ask them to compare any two cards. Make a note of the lower card, and ask them to compare it with one of the 98 remaining cards. Make a note of the lower card, and ask them to compare it with one of the 97 remaining cards. And so on. The lower card in the 99th comparison must be lower than all other cards, and thus is the 1 card. Likewise you can identify the 100 card after 99 comparisons, making a total of 198 comparisons to find both highest and lowest cards.

Can you find a method to identify the 1 and the 100 cards using less comparisons? What’s the optimal strategy?

  1. The rope trick

You are a burglar at the top of a 20m building, which has a ledge half way down on which it is possible to stand. There are hooks at the top of the building and on the ledge. You have a 15m length of rope and a knife. You can cut the rope if you like, and also make any type of knot anywhere on the rope, which uses up no length, and which can be placed on either hook.

How would you use the rope to descend the building safely? You are not allowed to jump off the building or the rope.

I’ll be back at 5pm UK. PLEASE NO SPOILERS. Please discuss your favourite knots.
