Odd number of pigs in cages

Dian, Pigs might. I think pigs would feel strongly about keeping their integrity; no non-integral pigs allowed. Though they might feel happier about non-integral cages.
Sam Bones, sorry, IT is no longer a safe haven from manual work - hadn't you herd?
Olaf, there are enough angry birds in my life.

==> 1.5 is considered an odd number?
Only if 1.5 is considered an integer.

Now I've also had the time to do a brute force attack on the problem. I was not separating cage topology from the rest of the problem in the same way, but made a brute force attack on the topology too: first I did compute 4 pig counts from 1-9 summing to 9 and put these counts right after a '{', which resulted in a raw solution like {p1{p2{p3{p4, then added 0 to the maximum number of possible cage closings '}' at each position.
I end up with only 74 solutions:
Will check within the next few days, which solutions I am missing.

Bye, Olaf.
One missing solution that's easy to spot is the one with all nine pigs in an innermost cage: {{{{9}}}}. More generally, it appears that all of your solutions have at least one pig in each cage. This is a requirement if the cage is standing alone, but a cage that contains nested cages can get all its pigs from the inner cages. So there is no requirement that an outer cage in a nest contain a separate quota of pigs.

Sam, all your pigs are facing us. For artistic reality, they should be at random angles.
Olaf Doschke
Programmer
Thanks, yes, I simply should also consider 0. This is how Sam Bones did make all his solutions the same string length. I should have looked closer there. Yes, and I did not yet remove permuations.
Bye, Olaf.
Bye, Olaf.
Olaf Doschke
Programmer
Ok, now I'm at 175 solutions including 0 in my nomenclature. Permutations should account for 87 of these solutions to be double solutions. {0{0{0{9}}}} surely is one solution without a permutation.
So, yes, separating cage topologies surely does simplify finding the distinct different solutions.
Bye, Olaf.

Bye, Olaf.
One of the ways I removed permutations is if there were two unnested cages, I would only print it if cage 1 was >= cage 2. That is...
{P1} >= {P2}
That means these would print...
{5} {1}
{3} {3}
...but this would not...
{1} {5}
That effectively removes the unnested cage dupes due to order.
I didn't have dupes like {1}{1}{6{1}} and {6{1}}{1}{1} because I hardcoded the topologies.

Thanks, Sam.
That's how I'd approach this, too. Sorting is always a good way to reveal permutations.
