"For some x" is the same as " exists x." Unlike in everyday language, it is does not necessarily refer to a plurality of elements, and so might be more clearly represented in colloquial English as "for at least one."

But I think this is not a very good algorithm, and it may have been original research. So I added citation-needed because we need an established algorithm from e.g. some book. <!-- Template:Unsigned IP --><small class="autosigned">— Preceding [[Wikipedia:Signatures\|unsigned]] comment added by [[Special:Contributions/213.16.80.50\|213.16.80.50]] ([[User talk:213.16.80.50#top\|talk]]) 14:42, 8 November 2016 (UTC)</small> <!--Autosigned by SineBot--> == Spam == Why the hell is there a picture of an aeroplane on this page? <small>—Preceding [[Wikipedia:Signatures\|unsigned]] comment added by [[User:Criffer\|Criffer]] ([[User talk:Criffer\|talk]] • [[Special:Contributions/Criffer\|contribs]]) 16:24, 11 October 2007 (UTC)</small><!-- Template:Unsigned --> <!--Autosigned by SineBot--> == Definition == Is there a kind of '''agreed''' definition on this term?

So most clusters (maybe 60~80 %) will have a similar number of elements, but the remainder will have very few or very many elements.
