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 , Xi + x3 = 4 . Given this equation , xi s 4 if and only if 4 - xy = xz 20.Page 212

The insight involves the coefficients of the

The insight involves the coefficients of the

**slack**variables and the information they give . It is a direct result of the initialization , where the ith**slack**variable xn + , is given a coefficient of +1 in Eq . ( i ) and a coefficient ...Page 484

The

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 actually can be used to calculate**slack**. ) ...### What people are saying - Write a review
