As is well known, "stir up" the brain to help a small but tricky puzzles, often referred to as "puzzles".Usually these are in the nature of the problem, rather logical than mathematical.What is the difference?The fact that in solving a mathematical problem you need to use, as a rule, one or more theorems, axioms, or recall the formula.Logical problems, too, are mathematical, but let's make the emphasis on puzzles that require ingenuity to solve them, the breadth of thinking and ignore the possibility to find the correct answer.
Puzzles are different, but is there one that causes more than one million people to work on a solution?Of course, the most difficult puzzle in the world there!Get ready to smash his head, not one night.
most difficult puzzle in the world: the battle of gods and men
The most difficult task is called a logical puzzle proposed by the American logician and philosopher George Boulos.It was first published in the Italian newspaper "Republic" in 1992.It is noteworthy that even Boulos gave inquisitive minds suffer to the same article, I put the puzzle solution.Thus, the content of the following logic puzzles.There are three gods who are familiar with each other (Boulos proposes to use the A, B and C in order): the god of lies, the god of truth and the god of the case.God says the truth the whole truth, the god of lies - the truth only God can speak as a case of truth and falsehood in an arbitrary order.We need to determine who is who, just by asking three questions, the answer to which involves only "yes" or "no."Each question can be asked only one god (ask all at once is impossible).Gods understand human language, but prefer to be responsible on his own.In their language there are two words - «ja» and «da», and we do not know what word is "no", and how "yes."
most difficult puzzle in the world: some explanations
Boulos also slightly expanded condition of the problem by adding the following points:
- God alone can specify more than one question.Thus, it may be that someone will not get any.
- next question can be formulated only after receiving a response to the previous one.
- case God chooses response to a question by flipping a coin, which is in his head.
- questions- "paradoxes" forbidden to ask, such as "You're answer« ja »?
most difficult puzzle in the world, clues to solving
philosophy and logic Boulos proposed to begin to calculate the lie of any God or God's truth.You can use complex logical relationships in question.For example, could be asked the following questions:
- Does that «da» - this is 'yes', despite the fact that you - the God of truth, and in - the god of the case?
- odd if the number of truthful statements in this list: «da» means "yes", you - there is a lie in - the god of the case?
Thus, the most difficult puzzle requires that you first determine which of the answers is "yes", and which - "no."Further, based on this, you need to go to a certain gods.By the way, you can identify one of the gods in the first issue (if you used one of the approximate options proposed above).We will not reveal all the secrets of the solution, because the hardest puzzle game you can be a virtue, if you meditate logically.Remember that you have only two questions.Formulate complex issues.Last god you define a process of elimination.
