Something like (in pseudocode):

To avoid large amounts of parentheses, would it work to have
NEGOTIATOR_PRE_JOB_RANK = ifThenElse( (Target.JobUniverse =?= 11), \
with the two helper expressions accordingly set? (NONPARALLEL* basically mimicking
the default one, "a - b*Memory - c*Cpus", PARALLEL* something like "x + y*Cpus - z*Memory")
I have searched the net and found that I had asked similar questions already 8 years
ago, but there were only more or less vague answers, nobody actually seems to _use_
