A truth table arranged so neighbouring cells differ in one Boolean variable, using Gray code order along each multi-bit axis. Opposite edges are also adjacent. A valid group contains all combinations of varying variables while every other variable stays fixed; it eliminates those variables and gives an implicant; covering the one-cells yields a disjunctive normal form. The method is associated with Maurice Karnaugh.

A Karnaugh map (K-map) is a visual tool used to simplify Boolean algebra expressions, making it easier to minimize logical functions without having to use extensive algebraic manipulations. It is particularly helpful in the design and optimization of digital circuits in computer science and electrical engineering. Here are some key points about Karnaugh maps: 1. **Structure**: A K-map is organized as a grid.
