• The map method of simplification is convenient as long as the number of variables does not exceed five or six. As the number of variables increases it is difficult to make judgements about which combinations form the minimum expression.
Limitations of K-maps

The map method of simplification is convenient as long as the number of
variables does not exceed five or six. As the number of variables increases it
is difficult to make judgements about which combinations form the minimum
expression. In case of complex problem with 7, 8 or even 10 variables it is
almost an impossible task to simplify expression by the mapping method. Another
important point is that the K-map simplification is manual technique and
simplification process is heavily depends on the human abilities. To meet this
need, W. V. Quine and E. J. McCluskey developed an exact tabular method to
simplify the Boolean expression. This method is called the Quine McCluskey or
tabular method.
