1 day ago · Alan Mathison Turing OBE FRS ( / ˈtjʊərɪŋ /; 23 June 1912 – 7 June 1954) was an English mathematician, computer scientist, logician, cryptanalyst, philosopher and theoretical biologist. [5] He was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation ...
4 days ago · Turing machines with just a few rules look pretty simple. How hard could it be to understand a program that fits on an index card? Brady’s Bunch of Beavers. The one-rule case is easy, because there are effectively only two possibilities. If the rule tells the Turing machine to halt when it sees a 0, it stops on the first step.
2 days ago · Imagine you're chatting with two hidden participants – one is a human and the other is a machine. You can only communicate through text messages. Your job is to figure out who is the human and who is the machine. If you can't reliably tell the difference, then according to the Turing Test, the machine is considered intelligent! A Lasting Legacy
2 days ago · Lambda calculus is Turing complete, that is, it is a universal model of computation that can be used to simulate any Turing machine. Its namesake, the Greek letter lambda (λ), is used in lambda expressions and lambda terms to denote binding a variable in a function .
4 days ago · Draw a Turing machine to find 1’s complement of a binary number. 1’s complement of a binary number is another binary number obtained by toggling all bits in it, i.e., transforming the 0 bit to 1 and the 1 bit to 0. Example: 1’s Complement. Approach: Scanning input string from left to right. Converting 1’s into 0’s.
2 days ago · The Turing Test is a thought experiment that proposes a simple yet profound way to assess a machine’s intelligence. It involves a human judge who engages in a conversation with two entities: one is a human and the other is a machine. The judge is unaware of which entity is which and communicates with them via text-based messages.
4 days ago · That's precisely what a decision procedure is, it's an algorithm that takes as input the description of a Turing machine, and an input, and returns true if and only if the Turing machine halts when given the input.
