10l cup, 8l cup, 5l cup.
Put 9l in the 10l cup.
Max 8 moves.
Pouring between cups is 1 move. Emptying cup is 1 move. Filling a cup is 1 move.

Do all cups start off empty? |

Nice one. I first found an 11 and 10 step solution, then the 8: | |

Actually I've nailed 11. 16 into 11 twice leaving the two fives, which gives 10 in the 11. Then poor in from the 8. I need a different approach for 10 and my mind can't find it. | |

I agree, and I'm willing to show why I found it obvious. | |

You're aware these things are usually pretty easy to solve from a computing point of view? |
11-23-2013 07:12 PM

Yeah, it would be a good exercise to direct a computer to solve the problem, and it may well be a better exercise to direct yourself. | |

You could just google the answer too! | |

I'm thinking you're making the mistake of assuming we're as unscrupulous as your fellow lawyers. Us basic folk like to enjoy the benefits of some genuine effort. | |

Yeah the quickest way to do this is the way that doesn't involve writing loads of shit down on a note file before thinking "what the fuck am I doing this for, just fill the 8 up, fill the 5 up from the 8, pour what's left in the 8 into the 10, empty the 5 down the sink, rinse and repeat" and have more time to do important shit. | |

I can do it in 6. | |

For a very short time I entertained the idea to write a program that would solve this for all combinations of sizes X Y Z and emount of moves N but then I thought "stop getting so distracted by stuff".. | |
| |
11-23-2013 11:46 PM

In fact I can do it in one move. | |

I woke up at night and had a eureka moment. Can now do it in 10. | |

The secret is getting 10 in the 11 in as few moves as possible. | |

I got it, also after sleep. I'd bet there's a higher chance of getting the answer after sleep (> after putting it down for a while > after working on it consecutively for some time) | |

Well it didn't take long to get to 11 | |
| |

I got it in ten if we can allow the 8 to overflow when pouring a full 11 cup into it, thus emptying the 11. | |

They're from an Android app called either water puzzle or water logic. It's free. There are 30 levels getting progressively harder. If you like logic puzzles it's a great little app to kill some time with. | |

| |
In fact, if you're really geeky and like logic games and competition, we could all dl it at the same time and race to get through levels. No way to police for cheating but you'd have to be a right loser to cheat, hmm maybe to even play. | |

lol apps, I fucking hate phones. I've never had a smartphone, don't want one. Last phone I had was a shitty old model a friend gave me so I could be contacted outside of facebook. And that's broke now after I had to dive into the sea to pull my friend out who got put on her arse by a monster wave that also soaked our fucking coats. That was a fun night. | |

Grunch and without counting how many moves this is, this is my first stab at it: | |
11-29-2013 04:48 PM
#37
| |
Okay, so I've counted the steps. You obviously have to empty the 10L before performing step 6 (pouring what's left in the 8L into the 10L), so I count 9 steps (if I'm counting right). | |
11-29-2013 04:53 PM
#38
| |
Another way to do it (still grunching, still not counting steps): | |
11-29-2013 04:54 PM
#39
| |
Fuck, 9 moves again, and I feel like I've mentally eliminated all the most likely seeming permutations. I'll start from scratch. -.- | |

A helpful way of figuring it out is to write down 2 numbers for every glass, ie if a 10l glass has 7l in it, the two key numbers are 7 & 3, which I always write as 7(3) because then you have a clear and easy to read way of stating the muber you can add to another glass and the number you can subtract from another glass. | |

Figured it out: | |
11-29-2013 05:34 PM

So my method for these sorts of things is to start with what I know about the first few moves of the puzzle and what I know about what the last few moves will have to be, and solve from there. | |

i fill the 10L up all the way. then stick my cock in to displace 1L of water. | |

Actually with the earlier levels you can't really help but do that but with the harder ones you have to think more. | |

Ok, you're right, but the value of the game doesn't come from those games. It comes from the really complex ones later on in the game where you'd be very unlikely to stumble on the solution. | |

I take it back. It is not a great game. It is a ridiculously frustrating game and I can't believe that having been through the ordeal of completing it once I've actually downloaded it again. | |

Grande 6 took me about 2 minutes but mad 6, which you're long past, has stopped me from pregressing. | |

If I just quit doing work entirely I can lick these lazors by c.o.b. Almost done with glassware. | |

That lazors rush was a lot of fun. Done with water logic basics too. | |

They were a good time. I remember the first day I started on lazors, I got caught on a puzzle and had a friendly dream reminiscent of lazors with a psychedelic colorpad of yellow greens, dull oranges, and dirty purples. I managed to solve the puzzle I was stuck on the moment I got to the morning loo. | |
