today i sat on a discussion between Jay and p. and been refreshed for the fact that i should have compiled the spatial allocation models and algorithms data into a first draft. well, so where is my first draft? the answer is, i keep delaying it since got quite many concepts in various field needed to read into. but for the moment, i think its enough. what i got at the moment already satisfying my thirst in querying. since what they say anyway, is when you write, you know what's missing and thus you can push your own knowledge boundary further.
