hi, just wanted to ask: is there a logical-ordered listing of the subjects in planetmath? The ordering modes that I've found in the site was order by subject index or alphabetically.
i'm looking for a list that enumerates all the prerequisite concepts before introducing a new one like:
02, 03-surjective map & injective map
05-set of natural numbers
I am looking for a faster algorithm for counting the number of data points that are close to a particular point in k-dimensional hyperspace? The current method of calculating all the distances to data points is too slow for my application to handle.
(If this should be posted elsewhere then please let me know)
Thanks in advance
