Exact algorithm

In computer science and operations research, exact algorithms are algorithms that always solve an optimization problem to optimality. Unless P = NP, an exact algorithm for an NP-hard optimization problem cannot run in worst-case polynomial time. There has been extensive research on finding exact algorithms whose running time is exponential with a low base. (Wikipedia).

Advice for prospective math researchers | Matrices: which exact algorithms should you know?

Algorithms with matrices are at the heart of linear algebra, and are a key resource for prospective research mathematicians, including amateurs. But in fact there is a big distinction in the world of matrix algorithms that is usually finessed, that we want you to be very aware of. That is

Learn to use summation notation for an arithmetic series to find the sum

👉 Learn how to find the partial sum of an arithmetic series. A series is the sum of the terms of a sequence. An arithmetic series is the sum of the terms of an arithmetic sequence. The formula for the sum of n terms of an arithmetic sequence is given by Sn = n/2 [2a + (n - 1)d], where a is
