The Lai-Massey Scheme is similar to a Feistel network in design, but in addition to using a using a non-invertible round function whose input and output is half the data block size, each round uses a full-width invertible half-round function. Either, or preferably both of the functions may take a key input as well.
In topology and in calculus, a round function is a scalar function, over a manifold, whose critical points form one or several connected components, each homeomorphic to the circle, also called critical loops. They are special cases of Morse-Bott functions.
Since a single round is usually cryptographically weak, many attacks that fail to work against the full version of ciphers will work on such reduced-round variants. The result of such attack provides valuable information about the strength of the algorithm, [9] a typical break of the full cipher starts out as a success against a reduced-round ...

The bifurcation diagram shows the forking of the periods of stable orbits from 1 to 2 to 4 to 8 etc. Each of these bifurcation points is a period-doubling bifurcation. The ratio of the lengths of successive intervals between values of r for which bifurcation occurs converges to the first Feigenbaum constant.
