Solving a cryptarithm by hand usually involves a mix of deductions and exhaustive tests of possibilities. Cryptarithmetic is a puzzle consisting of an arithmetic problem in which the digits have been replaced by letters of the alphabet. The goal is to decipher the letters (i.e. Map them back ...
xi is each individual value in your data set. ˉ xˉ is the mean (or arithmetic average) of all the values in the data set. N is the total number of values in the data set.How does this work?Calculating the Average: First, you find the average value of your dat...
The main reason for mentioning error-correcting codes here is not really for the codes themselves (which may be interesting, but probably more applicable for communications). Instead, these texts are some of the best introductions to Linear Feedback Shift Registers (LFSR's), arithmetic mod 2, ...

In 2019, we saw an explosion of activity in zero-knowledge proofs. This brief review for cryptographers surveys the field.

Verification: 5 pairing checks plus some elliptic curve arithmetic [toc-embed][zk] — Democratizing zk-SNARKs: Improved setup, performance and security (Sean Bowe) zkSNARKs in production software. zcash brought zkSNARKs to production last year. Very expensive — only people to production so far...
This stems from the notion that results from both approaches are still solving the same problem. The system 100 takes advantage of the above idea to use an arithmetic circuit that operates on the evaluations of all the F(x) and G(x) (previously known as the result ciphertexts) to reduce ...
