<0> In other words, there are a whole lot of numbers you can use
<1> infix 2 postfix
<0> Don't remember offhand, fronum.
<0> Infix, postfix, doesn't really matter for this problem
<0> 6 * 6 + 5
<0> Same length
<1> yes
<0> Basically
<0> If you had to teach a computer to come up with 8 5 * 2 +
<0> Or whatever
<0> The computer has to check each set of numbers independently
<0> It WILL hit 6 * 6 before it hits 8 * 4 or whatever, IF it starts at 1
<0> And you have to keep that in mind
<0> We missed 6 * 8
<0> The computer shouldn't
<1> using stack
<0> It has to check everything
<0> Well
<0> We're talking about an algorithm
<0> I don't think we have to walk too far into the "what's the nicest way to implement it"
<0> Stack, heap, recursion, iteration, data structure selection, whatever
<0> Let's figure out how to do it at all
<0> Then recursion or iteration or such will pretty much come up as they're needed, or when we get around to optimizing.
<0> Do you understand how I'm approaching this problem?
<0> That's really the critical lesson here.
<0> I don't give a damn if you even have a starting point on a postfix whatever algorithm tonight
<0> But if you gain some understanding about how to approach problems like these, you'll be better off
<0> Be confident that, if you can do something, then you can figure out how you're doing it.
<1> waking to his solution space , when it finds a solution , printing all the solution on this level
<0> I'm talking about more general.
<0> How would you come up with that sort of approach on an unfamiliar problem?
<0> Solve the problem, then figure out how you solved it.
<0> A large part of programming consists of figuring out how to explain to very demanding and stupid computers how to do things that we humans find utterly intuitive.
<0> I couldn't even begin to show you how to perform basic algebra without thinking about it for a while.
<0> So if somebody asked me for an algorithm to do algebra, I'd have to work on it.
<0> But the answers are there.
<0> I can DO algebra, so clearly I'm using some algorithms.
<0> Right?
<1> indeed
<0> Convince me that you really understand
<0> Explain to me in your own way what you've learned here about how to handle these problems
<1> so ...
<1> firt
<1> lets asume we starting with 1
<0> No no
<0> Forget the whatever, the postfix
<1> but how
<0> I'm not talking about that.
<0> You said you had three similar problems on the test
<0> Or something
<0> And that your weak spot is clearly how to approach the problem in the first place.
<0> Right?
<1> yes
<1> :(
<0> That's what I'm concerned about.
<1> well they are not like that one
<0> So:
<0> [02:54] <0> So if somebody asked me for an algorithm to do algebra, I'd have to work on it.
<0> [02:54] <0> But the answers are there.
<0> [02:54] <0> I can DO algebra, so clearly I'm using some algorithms.
<0> [02:54] <0> Right?
<0> [02:54] <1> indeed
<0> [02:55] <0> Convince me that you really understand
<0> [02:55] <0> Explain to me in your own way what you've learned here about how to handle these problems
<0> Coming up with any algorithm for just about anything
<0> Would you sit there and say "gosh, nothing leaps to mind, I give up"
<0> Or, what would you think instead?
<1> on this problem
<0> On any problem
<0> Any time you have to come up with an algorithm
<0> ***uming it's a problem you can understand, like this postfix one, or let's say an algorithm for how to perform, I don't know, long division.
<0> Whatever.
<0> The basic approach to formulating an algorithm for those tasks will be similar if not identical.
<2> Maybe what you should do is tree the number out into multiples of <=10
<0> Sheesh
<0> I'm talking about his mindset
<0> error, when you came in here, you were sort of wringing your hands and desperate
<2> And you could also do something like if < 20 also produce an add operation
<0> At least, that's how you sounded
<0> Since then, we've looked at your problem and come up with some starting point for maybe one approach to tackling it
<2> Then check the length of the two possibilities and whichever is shorter wins
<0> And you've said "indeed" a lot.
<0> But I don't think you're learning how to not look at this sort of problem and wring your hands in desperation
<1> :(
<0> I wrung my hands for a minute, checked in #math to see if somebody knew offhand, talked it over with danielson and you, but ultimately, where did I find my starting point?
<2> Jblitzen, where did your nick come from anyways?
<0> I'll paste where I got my starting point at the solution, error
<0> And it has nothing to do with numbers
<1> i'm not good at maths
<0> [02:15] <0> I'm coming up empty on how to even start
<0> [02:15] <2> Obviously, you're going to want to have priority for multiplication
<0> [02:16] <0> Actually, I lied, I do have a starting point
<0> [02:16] <2> ...since that's going to yield smaller results
<0> [02:16] <0> Whenever trying to figure out an algorithm of a task you can do by hand
<0> [02:16] <0> Do it by hand and then figure out how you did it
<1> that's why i come here
<0> Remember that, error?
<0> danielson, "Blitzen" is phonetically similar to my actual last name
<1> yes i doo
<0> I used to use my first initial and last name as my nick
<0> JB was a holiday nick that I decided I liked and vastly preferred to the potential identity risk of using my real name
<0> So now I'm a magical reindeer
<2> I see...
<0> error, do you see, in those lines I pasted, any math?
<0> I could have been talking about a cooking recipe.
<2> ...and if you piss someone off you become JBitchin or "Just Bitchin" :)
<0> Or how to change the oil in my truck.
<0> Pfft, everyone tries the JBitchen
<0> It just makes them look bad
<2> I don't mind looking bad...it's just an obvious pun
<0> Do you see my point, about cooking recipes, or oil changes, error?
<0> The primary problem you faced isn't the actual mathematical problem on that worksheet.
<0> It was how to APPROACH the problem.
<0> And not just run off and give up because it seems mathy.
<3> JBlitzen
<0> Do you understand what I'm working awfully hard to explain to you, error, with absolutely no reason to other than generosity?
<0> What, non
<2> Blitzen, do you still prefer Fox News?
<3> Are you a neocon?
<0> What do you mean do I still prefer Fox News
<4> yes i understand you why you want me to think first
<0> I've watched maybe two days of foxnews in my life
<3> what a liar
<2> I remember talking to you once about Fox News being unbiased blah blah blah
<3> I got your back danielson
<2> I chocked it up to Republican flank watching...
<0> error, look at your problem description again, and tell me how you plan to approach it. When I say "approach it", I don't mean, what algorithm are you going to use. I mean, how are you going to look for an algorithm?
<2> I'm not arguing or trying to start one, just checking my memory
<0> Fox News is unbalanced
<0> er
<0> Eh
<0> Fox News is unbiased
<2> Why do you believe that to be true?
<0> Most of their hosts and guests have strongly biased positions, just like on CBS or ABC, except on Fox News, you're informed of their positions, and they come from both sides of the spectrum.
<5> zarqawi is dead
<0> So that I can watch Fox News and know exactly how to interpret the source of anything being said
<0> He is, static?
<4> i need to think at N posibilities
<5> put it on cnn
<4> and using the finest one to it
<0> error, can you do the mathematical task yourself?
<0> I mean, when I gave you 42, you seemed to be able to produce the corresponding representations
<0> Holy ****, static, thanks
<4> but i don't have the answer for that one
<4> how i got there
<5> very surprising
<4> mathematically talking
<0> error, I didn't know either.
<3> JBlitzen: i think danielson may be a racist
<0> In fact, I spent about ten minutes repeating that "I know the answers, but I have no idea how I'm getting them"
<0> Right?
