comment Least absolute deviation for item prices
Is it possible to minimize $\|Ax-b\|_1$ by taking the derivative and setting it equal to zero? Such as when I use least squared error?

Hi, this is what I suspected. But because of the wording, I wasn't sure there was only one position for each committee. Thank you.
