When working with Karnaugh maps one must always keep in mind that the top edge " wrap arounds " to the bottom edge, and the left edge wraps around to the right edge the Karnaugh diagram is really a three-or four-or n-dimensional flattened object.

Once the propositions are reduced to symbols and a propositional formula ( ~ ( y & z ) & ( x ?! y ) ), one can construct the formula's truth table; from this table the Venn and / or the Karnaugh map are readily produced.

While this example was easily simplified by applying normal algebraic methods [ f = ( a'+ a ) b c ], in less obvious cases a convenient method for finding the minimal PoS / SoP form of a function with up to four variables is using a Karnaugh map.
34.
But further attempts to minimize the number of "'literals "'( see below ) requires some tools : reduction by De Morgan's laws and truth tables can be unwieldy, but Karnaugh maps are very suitable a small number of variables ( 5 or less ).

In his 1952 paper " A Chart Method for Simplifying Truth Functions ", Veitch described a graphical procedure for the optimization of logic circuits, a year later ( 1953 ) refined in a paper by Maurice Karnaugh into what is now known as the " Karnaugh map " method.

:I agree about the TeX . There a whole lot of ( La ) Tex packages out there that support typesetting technical things like chemical structures, syntax trees, mathematical plots, Feynman diagrams, phonetic symbols, Karnaugh maps, etc, that would otherwise have to just be made by hand and uploaded as an images.

Each minterm can be found on the Hasse diagram, on the Veitch diagram, and on the Karnaugh map . ( The evaluations of " p " shown in the truth table are not shown in the Hasse, Veitch and Karnaugh diagrams; these are shown in the Karnaugh map of the following section . ) 2 = 2 10.

Before it can be presented in a Venn diagram or Karnaugh Map, the Euler diagram's syllogism " No Y is Z, All X is Y " must first be reworded into the more formal language of the propositional calculus : "'It is not the case that : Y AND Z'AND'If an X then a Y'".
