A sentence

[nyggus]

1. “Smith (1999) listed algorithms A and B (for the latter, see also Senvy (1975) or Bevyugh (1979)).”
2. “The procedure constructs groups on the basis of certain rules, which not necessarily reflect the aims defined by the problem studied.”
Are these sentences correct?

Thanks,
Nyggus

*I think in the second sentence, ''don't'' is necessary:

.........., which don't necessarily reflect.....
