A Karnaugh map (KM or K-map) is a diagram that can be used to simplify a Boolean algebra expression. Maurice Karnaugh introduced it in 1953 [ 1 ] [ 2 ] as a refinement of Edward W. Veitch 's 1952 Veitch chart , [ 3 ] [ 4 ] which itself was a rediscovery of Allan Marquand 's 1881 logical diagram [ 5 ] [ 6 ] (aka.
Maurice Karnaugh (/ ˈ k ɑːr n ɔː /; October 4, 1924 – November 8, 2022) was an American physicist, mathematician, computer scientist, and inventor known for the Karnaugh map used in Boolean algebra.
The general digital computer community chose the Karnaugh approach. Veitch accepted this decision, even though in early 1952, before his presentation, he had almost changed to that approach but decided against it. A few years later several textbooks described the K-map, a few of them designating it a Veitch diagram.
Yes. The Karnaugh map is useful for showing logical relations between Boolean data types that take only values "1" (true) or "0" (false). Elementary Logic gate functions such as AND, OR, NAND, NOR, EXOR, etc. can be mapped, also combinations of connected gates if they are not too complicated. However Boolean data is abstract and the "1" and "0 ...
Although more practical than Karnaugh mapping when dealing with more than four variables, the Quine–McCluskey algorithm also has a limited range of use since the problem it solves is NP-complete. [22] [23] [24] The running time of the Quine–McCluskey algorithm grows exponentially with the number of variables.
Don't-care terms are important to consider in minimizing logic circuit design, including graphical methods like Karnaugh–Veitch maps and algebraic methods such as the Quine–McCluskey algorithm. In 1958, Seymour Ginsburg proved that minimization of states of a finite-state machine with don't-care conditions does not necessarily yield a ...

In the early days, logic design involved manipulating the truth table representations as Karnaugh maps. The Karnaugh map-based minimization of logic is guided by a set of rules on how entries in the maps can be combined. A human designer can typically only work with Karnaugh maps containing up to four to six variables.
