Minimum of cosine sum

Read Original

The article investigates the minimum value of a function f(x) defined as the sum of cos(kx) for integer k from a set A. It discusses the Chowla cosine conjecture, which posits a lower bound, and examines specific cases like using prime numbers or random sets. The author includes Python code for numerical exploration and discusses scaling challenges and potential polynomial-based solution methods.
