I'm bored so I'll share some random brain puzzles I remember. If you are confident you know the answer, please use spoilers as to not ruin the puzzle for others. You have 2 ropes of an unidentified material and a box of matches. The material has a non uniform burning rate, parts of it burn faster than others, however you know each one takes exactly 1 hour to burn from end to end. How can you measure exactly 45 minutes with the 2 ropes and box of matches? --- Go and watch Ef ~ A tale of memories now! ... Copied to Clipboard!

EyeWontBeFooled posted... Moar You have 2 identical robots that are separated apart by an unknown distance. You know there is a button between them (that does nothing) and the robots can only move left or right. This diagram might help: [0.0] = robot * = button _ = one unit of space ____[0.0]______*_________[0.0]______ You need to command the robots in such a way that they can meet each other; however both robots will share the same instructions. If you tell them move right then both will move right at the same time and same distance. --- Go and watch Ef ~ A tale of memories now! ... Copied to Clipboard!

call the button tech to come repair the button. after all it is clearly obvious that the button is designed to get the robots to meet once it's pushed, so long as it is operative. it is clearly obvious that this one is currently inoperative --- Debussy understood that a work of art, or any effort to create beauty was always regarded by some people as a personal attack ...

Place the button on the right side of the right robot as to blockade that one from moving the same as the left robot when having them both go right? I think I said right on that far too many times. But am I right? :) ... Copied to Clipboard!

You cannot physically move the robots or button. The button is also small enough that it wouldn't block any robots from moving. You can only give them the same order(s) and multiple orders if you want. To clarify, Extra tip: --- Go and watch Ef ~ A tale of memories now! ... Copied to Clipboard!

Commanding them to both go left, right, or remain motionless together, no matter how many times you do this, they will always be equally distant from their starting separation. Something needs to impede one of the robot's progression. Unless you're wanting us to bend space and/or time, because not even thinking in three dimensions could this be solved the way your problem is stated. ... Copied to Clipboard!

There's a solution and it's not bs like bending space time although fun theories are welcome. toreysback answer is pretty close. Here's the key part of their comment toreysback posted...

The puzzle really doesn't give enough information to be interesting as stated. Either the robots cannot be instructed to move relative to the button and the puzzle is impossible, or they can and the instruction "move to the button" has them meet trivially. Note that, if the robots can only process a command in the form "Move left until you are on the button" or similar, the puzzle becomes only conditionally possible, as giving a command like this without a max duration results in one of the robots getting stuck on this instruction forever, while including a max duration makes the solution not work if the button takes longer to reach than that duration. --- "That is why war is so tragic.

[LFAQs-redacted-quote] Technically you are right kirbyy posted... Tell them to both move towards the button Also could work the way I described so its technically correct it but see above on what robots can or cannot know if you want an extra challenge. Steffenfield posted... Once a robot reaches the button, smash it with a hammer. Lmao, kudos on thinking outside the box and just turning one of them the opposite direction! That'd work. For the purpose of the puzzle, assume the robots are very heavy and you can't lift them up or move them by hand. You are almost there though: the_rowan posted... if the robots can only process a command in the form "Move left until you are on the button" or similar, the puzzle becomes only conditionally possible, as giving a command like this without a max duration results in one of the robots getting stuck on this instruction forever, while including a max duration makes the solution not work if the button takes longer to reach than that duration. Close, CE is on the right direction, I think most of you already got the first part right and are just missing the second half of the solution. --- Go and watch Ef ~ A tale of memories now! ...

Is it one of those detective rooms where the mirror is a double sided mirror? If so I guess use the table to break the mirror and escape throught it. If not, is there anything else in the room? Like a vent so I dont die of asphyxia? How did I get into the room in the first place? What materials are the floor, ceiling, and walls? --- Go and watch Ef ~ A tale of memories now! ...

Pull the battery out of the first robot that touches the button. With that logic though, why not just kill the power on one of them initially? Build a homeless shelter next to one of them, and send inputs going in that direction. They both can't progress past that area. Did I mention that I hate this puzzle? ... Copied to Clipboard!

the_rowan 07/16/22 4:38:29 PM #36: |
So you can get the robots to meet like this: (assume N has an initial value greater than 0). Move left for N seconds Multiply N by 3 (or any value greater than 2) Move right for N seconds Multiply N by 3 Loop If at any point you are on the button, stop in place and do not follow further instructions. It's inefficient as hell but should work even if the button is arbitrarily far away. --- "That is why war is so tragic.

So you can get the robots to meet like this This is close enough, so its correct! You cant tell them to move X amount of time (that's not an available instruction) but the answer is pretty much the same: Kudos to you for getting it right, it is not an easy answer.

New puzzle: You are carrying 3 boxes: one with apples, one with oranges and the other with both apples and oranges. A co-worker plays a prank and labels all of the boxes incorrectly so that you dont know what is in them. For example the first box has an "apples" label, the second oranges, and the third says apples and oranges. You cannot see inside the boxes but you can ask for a sample fruit from them. For example you could ask to get a fruit from box 1 and get an orange. What is the minimum amount of fruits you need to sample before fixing all labels? --- Go and watch Ef ~ A tale of memories now! ... Copied to Clipboard!
