ONI should start an ambitious search for any clues of a hidden entity - accidentally divulging too much information via seemingly innocuous inconsistences in travel, engine signature, etc. I wonder if the MA shied away from using the junctions during Lacoon. Wanting to avoid the sparse traffic where more time could be spent eyeballing them.
Cross reference everything now that everyone's happy that the Interstate Hwy is reopen.
I'm thinking in all probability that they already keep the signatures since it's prudent. However, considering the amount of traffic and the analysis needed to find the 'odd' freighter or ship isn't easy.
I've seen this argument a number of times over the last 5 decades or more I've been reading SF (plus a collection that went back a couple more decades). It always assumes that if you've got x number of items, you need to do x**2 (x * x) full comparisons.
Absolutely not. The first thing anyone with that kind of massive search problem does is to try to sort the data into similarity classes so the number of items that needs to be compared is reasonable. How this is done varies wildly by the data domain, of course.
In this case, there was a suggestion to pull frequent visitors out of the data set, or at least collapse their signatures into a single entry rather than let them occupy multiple slots. Seems reasonable to me.
