I'm making a calender for a poolcompetition. There are 13 teams, they all have to play each other in a double Round Robin. So with home and away matches. But there are some conditions...

The teams (fake names) with the day they play their home matches:

Dragons A : monday
Dragons B : wednesday
Dragons C : w
Hobbits A : m
Hobbits B : m
Hobbits C : m
Hobbits D : w
Monkeys A : w
Monkeys B : w
Elves : m
Dwarves : m
Kiwis : m
Clowns : w

Conditions:

Dragons B and C can't play home together
There can only be 2 Hobbits teams at home together
Monkeys can't play home together
Teams must play alternate home / away as much as possible. Teams should not play home or away 3 times in a row.

I've tried some generators and other systems, but no luck so far... anyone has an idea how to accomplish this?
