Re: Vertical bar and colon "such that"?

hi, thx for rply

min function compute minimal element from the set.
How can I "translate" from "math language" to english, set property between brackets { } ?

for example: (attachment)

after i have colon sign, and i'm confused.. how can i read colon sign ? "such that" ?
so in my whole sentence i have to times "such that" but with different sign ? once colon sign later vertical bar ?

in other words: what element belongs to this set (between bracket { } ) ?

What you have written doesn't actually make much sense! It appears to be defining "n" but then there is mention of a "j"!

I would try to write it as
$\{n \in N | if e_k \in E_i', then k< j\}$
But I don't see what the "if then" has to do with n!"

Re: Vertical bar and colon "such that"?

hmm, thx for rply, i get this equation from this paper:
On the Automatic Layout of Data Flow Diagrams, page 43 (or 31), bottom.

yes, but "j" is defining in foreach loop, "j" is indexer variable
