Hi
we want to substitute multiple variables, for example x1x3 would be z1, x2x4 would be z2 and so on.
We save all combinations of monomials in a dictionary, then we wanted to use subs to replace the variables, but it does not work. How could one implement this?
The purpose is for linearization of a large system of equations. A system like this: x[1] + x[1]x[2]x[3] + x[1]x[4]x[6] + x[1] + x[4] + x[5] + x[7], x[0]x[1]x[4] + x[0]x[1] + x[2]x[4] + x[3]x[5]x[6] + x[3]x[5] + x[7] + 1, x[1]x[2] + x[2]x[3]x[6] + x[2]x[4] + 1, x[0]x[5]x[6]x[7] + x[1]x[7] + x[2] + x[7], x[1]x[3]x[7] + x[4] + x[5]x[6] + x[6], x[1]x[3] + x[2]x[4] + x[3]*x[4]
