Jan9 comment The smallest set of unit- length closed intervals that contains all of the given points@dtldarek no it's not a homework for math, but i need it for designing an algorithm. i have already written my program. but this time i want to find intervals before searching trough the set.

Tnx for your clear and complete explanation. I will vote up as soon as i get 15 reputation.
