Golomb ruler

A Golomb ruler is a set of marked points along a straight line such that the distances between every pair of points are all different. In other words, no two pairs of marks measure the same length. The goal is often to use the fewest marks possible while covering a specific length, which can optimize measurements or signal arrangements. It's like arranging rulers with unique segment lengths to efficiently measure distances or encode information without ambiguity. Golomb rulers have applications in fields like communications, coding, and network design for their optimal and unique spacing properties.
