It's a well-known algorithm.
This result guarantees the optimality of many well-known algorithms.
But Algorithmic trading is more related to how to trade an order or a set of orders, using a set of well-known algorithms.
Integer division algorithms compute the quotient and remainder given two integers, the most well-known such algorithm being long division.
It turns out that there is a well-known algorithm, the Gale-Shapley algorithm, that can be used to find an "optimal" matching of partners.
You press the button, then you get a six-digit code, which is running a well-known public algorithm, but with an unknown secret key.
Several well-known algorithms for hidden Markov models exist.
Kotsiantis et al. (2006) present a well-known algorithm for each step of data pre-processing.
