Forgot the newest topic?

Hello!

I guess the newest topic, Logic (Beta) , was introduced a month ago. Though I find members contributing to the section,but the contribution rate is very low. Apart from Mathematics and Physics, Logic should also be given equal importance. I would like to encourage the Brilliantians to contribute to the section with both easy and difficult problems. This would also give a chance to the members to level up and workout their brain!

Please do comment and share your views! ...And keep Puzzling!

Okay, here's one

Propositio de homine et capra et lupo
(A proposition about the man, and a she-goat and the wolf)

A certain man needed to take a wolf, a she-goat and a load of cabbage across a river. However, he could only find a boat which would carry two of these at a time. Thus, what rule did he employ so as to get all of them across unharmed?

Now, this one is really old. But it's a start.

Wouldn't it be "carry one of these at a time"? Otherwise the man would just take the wolf and cabbage across first and then go back for the she-goat, making for 3 crossings in total. If he can only take one at a time then I believe this would involve 7 crossings.

I was thinking of a variation of this, where the man has animals A,B,C,D,E, where A only eats B, B only eats C, C only eats D and D only eats E, (E is a vegetarian, or perhaps a vegan). If he can take a maximum of two animals at a time across the river, then I find that he can do it while keeping all the animals alive in 9 crossings, although I'm wondering if that is the minimum or not.

This problem and wording actually dates back to year 782, Alcuin of York being the author of the book "Propositiones ad Acuendos Juvenes". That is the exact wording, as translated from Latin. By "carry two of these at a time", that includes the man, so unless the wolf, she-goat, or the cabbage can handle the boat, the man has to go on each trip and carry just one other with him. So, here's how it can go, from side A to side B

1) She-goat to B
2) Back to A
3) Wolf to B
4) She-goat back to A
5) Cabbage to B
6) Back to A
7) She-goat to B

@Michael Mendrin Ah, o.k.. I had read "just two of these" as referring only to the wolf, she-goat and cabbage but not the man himself. I suppose that there were no self-steering boats back in Alcuin of York's day. :)

@Michael Mendrin What does make you a genius?

@Swapnil Das What will make me a genius? A brain transplant, using Albert Einstein's brain. But, alas!, it seems like his brain, which was supposed to be in a jar somewhere, has been lost!

I would also like more problems in logic ( beta) part.... I have become level three in it, but now Very few questions are left to be done. I would also support this view because I would like more questions in this specific section...!!! Hope something will be done soon.😊😊😊
