Bidirectional transformation

In computer programming, bidirectional transformations are programs in which a single piece of code can be run in several ways, such that the same data are sometimes considered as input, and sometimes as output. For example, a bx run in the forward direction might transform input I into output O, while the same bx run backward would take as input versions of I and O and produce a new version of I as its output.

Inverse function

In mathematics, the inverse function of a function f is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by f − 1 .

Reversible computing

Reversible computing is any model of computation where every step of the process is time-reversible. This means that, given the output of a computation, it is possible to perfectly reconstruct the input.
