Response to the following problem:
How many Fixed-polarity Reed-Muller expressions there are for functions of n = 3 variables? Determine all them for the function given by the SOP-expression
f(x1,x2,x3) = x¯1x2 + x1x3 + x2x¯3 + x1x2x3,
and compare their complexities in terms of the number of non-zero coefficients.
Make sure you use enough details to support your answer.
