Typical hash functions take inputs of variable lengths to return outputs of a fixed length. A cryptographic hash function secures the message-passing capabilities of hash functions. Hash functions ...

Recall that a function can be thought of as a machine which takes an input in (say x) and then depending on what that input is, it returns an output (say y) by some predefined rule (say f). The graph ...

In mathematics, a "well-defined" function is one where there is only 1 output for a given input (as a side note, you can have only single input functions, and still semantically get multiple ...

Investopedia / Zoe Hansen A hash is a mathematical function that converts an input of arbitrary length into an encrypted output of a fixed length. Thus, regardless of the original amount of data ...

The Rosenbrock function, also referred to as the Valley or Banana function, is a popular test problem for gradient-based optimization algorithms. It is shown in the plot above in its two-dimensional ...
