Читать книгу Reversible and DNA Computing - Hafiz M. H. Babu - Страница 18

The multiple‐output Boolean function of n Boolean variables is called reversible if:

1 The number of outputs is equal to the number of inputs.

2 Any output pattern has a unique pre‐image.

In other words, the functions that perform permutations of the set of input vectors are referred to as reversible functions.
