This application solves Karnaugh Map also called Kmap for 2 3 4 or 5 variables. It is the only application I know that will provide (and show on Kmap) ALL possible kmap solutions. It will also shows four different versions of an optimized output logic circuit: a tradicional version a circuit with common inverters and NAND/NOR only circuit.

If you like this application please consider buying the FULL version. It's cheap and it would help support this application:
