The slack variable for this constraint is defined to be x3 = 4 – x1 , which is the
amount of slack in the left - hand side of the inequality . Thus , x1 + x3 = 4 . Given
this equation , xi s 4 if and only if 4 – xy = x3 = 0 . Therefore , the original
constraint ...

Even when the simplex method has gone through hundreds or thousands of
iterations , the coefficients of the slack variables in the final tableau will reveal
how this tableau has been obtained from the initial tableau . Furthermore , the

This figure makes it easy to see how much slack each activity has . The slack for
an activity is the difference between its latest finish time and its earliest finish time
. In symbols , Slack = LF – EF . ( Since LF – EF = LS - ES , either difference ...
