käänteiskartta
Käänteiskartta, also known as an inverse map or reverse map, is a concept in mathematics and computer science that refers to the process of finding the preimage of a given set or element under a function. In other words, it involves determining the set of all inputs that map to a specific output under a given function. This concept is particularly useful in various fields such as cryptography, data analysis, and optimization problems.
In a more formal context, given a function f: X → Y, the inverse map of a subset
The concept of an inverse map is closely related to the idea of an inverse function, which
