in reply to Re^2: Sets of subsets
in thread Sets of subsets

Just look at the group t1 is in. t1 can be a group in itself. Or with each of t2, t3, ..., tk. Or any combination of them. Which means that if you have N "things", there are 2N-1-1 ways to be t1 in a group with other "t's" (-1 comes from that you seem to exclude the subset of all things together). And that's not even counting the different ways you can split up the group of things that aren't in the subset t1 belongs to.

    Definitely a good point. However, I'm sort of used to analyses sometimes taking upwards of days, so "blowing up" I guess might mean something else to me. You are correct though, very computationally complex. This was really just a random thought I had, I was wondering what sort of information I could extract out of this data. I imagine I'll end up going with a k-means clustering or something of that nature.

Discipulus anyway xp is still the best lowend game machine
[Discipulus]: both: everyting must be identical in the new v-machine
[Lady_Aleena]: So putting a nice DE or WM up on a Linux machine is not an option?
[Discipulus]: i need some converter to have directly an OVF format directly: at the moment i'm trying with vmware converter standalone
[Lady_Aleena]: I don't know what to tell you. I can barely get my Linux machine to do things I want.
[Discipulus]: if DE or WM means desktop env and win manager.. no, not an option
[Lady_Aleena]: That's what they mean, at least to me. 8)
[Discipulus]: in the first attempt i failed, with an not usable v-machine.. ;=)
[Discipulus]: but then discovered a registry trick to do before the physical2virtual migration
[Lady_Aleena]: Sounds like a headache.
