Re: Lower Bound ProofsI'm going to be attempting to illustrate something that I've waved my hands at, and really should have covered first. Then hopefully we can move on to some more interesting problems. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #32 20070806 04:53:41
Re: Lower Bound ProofsSorry, must have overlook this. Yes, those are correct. So here is the thing about models. We have two models: "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #33 20070806 05:19:11
Re: Lower Bound ProofsI suppose it depends on how much easier it is to compare the items than to switch them. Why did the vector cross the road? It wanted to be normal.
