Question #691907 on Yade changed:
https://answers.launchpad.net/yade/+question/691907

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

> for i in O.interactions:
>  if i.isReal:

"if i.isReal" is not needed, as "i" is guaranteed to be real, because
"iteration silently skips interactions that are not real" [1]


an approach could be using Python sets [2] (efficient, elegant, ...):
###
iniIntrs = set((i.id1,i.id2) for i in O.interactions)
... # some running
curIntrs = set((i.id1,i.id2) for i in O.interactions)
brokenIntrs = iniIntrs - curIntrs
###

cheers
Jan
