The set up you have is different from mine, you're set up shows :
_ _/ _ _ _
t t h h h
Where as I had
_ _ _/ _ _
t t t h h = F --> Chair (tenant)
The constraints said that there should be at least two from each group and that the chair person was to be part of either a tenant or home owner. And that the chairperson would have to be from one of the those two groups?
Did I misinterpret the rules?
My reasoning followed like this :
If F is the chairperson, the the committee would look like this.
F G K / Q _ (R/S/P)
Having G there forces K to fill the spot the extra spot that J or M couldn't have filled. F, already filled in as the chairperson, we have have need two tenants and two home owners now.
