This seems like the only general approach to factoring numbers, and for centuries, that was what people thought. However, in the past several decades, we have come up with fiendishly

Classical cryptosystems such as RSA and ElGamal can be broken easily using a quantum computer, so in this respect quantum computers help eavesdroppers and attackers. On the other hand, there are new cryptosystems in a quantum world that are . unbreak

In particular, we will see a method for breaking substitution ciphers that is fully automated. It won’t necessarily solve the cipher fully, but it will tend to get sufficiently close that fixing it at the end by hand will

How to Implement AI Responsibility?,The next cipher we will look at, known as the ., is based on matrices. It is a form of a substitution cipher, except that it doesn’t just substitute one . for another but rather one . of letters for another. For example, it might swap some three-letter block with another three-letter block.

Dendritic-Cells

How to Implement AI Responsibility?,When we do a computation, we would like to do it as fast as possible, or at least pretty fast. In order to talk about (roughly) what that means, we need to introduce big . notation. Let .(.) and .(.) be two functions, we say that . if there is some constant ., which does not depend on ., so that .for all ..
