First , all the tied basic variables reach

**zero**simultaneously as the entering basic variable is in- creased . Therefore , the one or ones not chosen to be the leaving basic variable also will have a value of**zero**in the new BF solution ...Page 200

A BF solution is said to be degenerate if any of these m variables equals

A BF solution is said to be degenerate if any of these m variables equals

**zero**. Thus , it is possible for variable to be**zero**and still not be a nonbasic variable for the current BF solution . ( This case corresponds to a CPF solution ...Page 726
