> The rule-based placement fails on an empty node (core count = 0) with condition 'cores:<1'.
> It also fails if current core number is equal to the core number in the condition - 1. 
> During the placement strategy process, the core counts for a node are incremented when all the rules match.
> At the end of  the code, an additional verification of all the conditions is done (with incremented core count) and it fails.
> I don't know why this condition is needed and removing it seems to fix the issue.
