Involutory function
Web1 mrt. 2024 · An involution, also called a self-inverse function, is a function f that is its own inverse, i.e., f ( f ( x ) ) = x holds whenever f ( x ) is defined. The paper presents a computational model of involution as a variant of Turing machines, called a time-symmetric Turing machine. Web1 mrt. 2024 · As every involutory function is injective, a time-symmetric Turing machine is defined as a special kind of reversible Turing machine. The tape reduction on the time …
