  1. In Topic: I need datastructure inspiration

    Posted 2 Sep 2015

    Yea I came here to say database. The answer is a database. Another data structure you might consider is a bimap which C++'s boost library also implements. Looking more stuff up I found the far more general multiindex data structure which basically attempts to implement the best possible structure to do what you need it to do. This is probably a pretty good pick. Multiindex is basically an in memory, compile time optimized, highly specific, database. C++ has some neat stuff if you can put up with the overwhelming complexity of it.
  2. In Topic: Inscriptions for the future..

    Posted 28 Aug 2015

    Either the X combinator or the Y combinator probably. Or just the definition of lambda calculus and the beta reduction rule. Hard to choose. Maybe all 3. They are the most beautiful bits of mathematics in existence, and indeed thought IMO. I've often thought of using the Y combinator as my epitaph. I can't commit to getting a tattoo of it because something better might come along in my life but if I were to die right now I would want that on my tomb stone.
  3. In Topic: Artificial Intelligence assignment

    Posted 22 Aug 2015

    There are tons of ways you could do that. You could for instance simply maintain a feature vector for bays net and then marginalize over the unobserved information to estimate the probability of the traffic being "abnormal". If this probability is greater than 50% then you assume that the traffic is abnormal. This would only require that you learn bays nets, some numerical computation methods, and to think up the right features. The more work you put in to the features and the structure of the net the better your system will be. Knowing your background would help be more specific however (as already noted).

    Cool picture. Was there a point?
  5. In Topic: Challenge: Create a new "infinite" data structure

    CTphpnwb has the right idea.

    Also implementing an infinite version of conway's game of life would be awesome. I hear quad trees are really good at managing that sort of thing efficiently.

    I do want to draw a distinction however. Conway's game of life at any given time always finite state so it is a kinda bad example. However the space that the cells move in *IS* a good example because the space could go on forever. You could make a point of making the finiteness of your space explicit in your implementation *OR* you could perform the abstraction of pretending like it is infinite! This is where the theoretically interesting stuff comes into play and where I want to push you to make an abstraction. Do not allow yourself to look at how much space is being represented at any given time; abstract that away. Once you have abstracted away the size it actually fits the idea of an infinite space.

    No witty rep meaning at the moment. Though 1415 AD was memorable, that's the year Jan Hus (John Huss) was burned, an event which pushed his followers (later known as Hussites) to fight. Hussite Wars were a bloody period, but mighty interesting. ;)

    Now your rep says you're "lala" :P That could mean "a doll" where I'm from. Yes, it has more than meaning here too... ;)
    So, how's it going, doll? ;p

    Then I would go legitimately subtle... like "speling expert" or "spelling export" .... drop or change ONE letter... hence, subtle.

    Your title would be WAY funnier if there was a spelling error in it.

    What's an esoteric hack? O.O
    What's a purely functional programming language? I've never used one before but they sound interesting . . .
