Number theoretic algorithms | Group theory
In group theory, a branch of mathematics, the baby-step giant-step is a meet-in-the-middle algorithm for computing the discrete logarithm or order of an element in a finite abelian group by Daniel Shanks. The discrete log problem is of fundamental importance to the area of public key cryptography. Many of the most commonly used cryptography systems are based on the assumption that the discrete log is extremely difficult to compute; the more difficult it is, the more security it provides a data transfer. One way to increase the difficulty of the discrete log problem is to base the cryptosystem on a larger group. (Wikipedia).
This came as a surprise. Although it looks like an example with smooth time-stepping, it is not. It is with original, simple time-stepping. I'm not exactly sure what this means. Maybe my smooth time-stepping method is superfluous.

David Harvey: Recent progress on deterministic integer factorisation
Abstract: There are several deterministic factoring algorithms of complexity N^(1/4+o(1)) going back to the 1970s. Last year Hittmeir lowered the exponent to 2/9, and I subsequently improved it further to 1/5. In this talk I will explain the key ideas behind these new algorithms. --------
