I have two lists liste = {x, -y, y, -z} and listv = {1, -2, 3, -4}, which represent the inequities obtained evaluating liste - listv <= 0. How do I reassemble or join those two separate lists into a more readable one having the form {x <= 1, 2 <= y <= 3, z >= 4}?
I further require that, when an expression comes with both a lower bound and a upper bound like the y above, it should not be written in two separate equalities y >= 2 and y <= 3, but in the more compact form 2 <= y <= 3.
