Mathematically-troubled Computer Scientist?
-
The logical thing that I would do is run both algorithms in the same machine and get the total running time then benchmark the two algorithms. I realize that this is not the "scientific" way of doing this. One should be able to say that "My algorithm is linear while the other guy is quadratic". :doh:

Because that doesn't give you the same information. An O(n) algorithm might appear faster than an O(1) algorithm if n is small and O is considerably larger in the second case. I've spent entirely too much time in the past few years cleaning up old code written to retrieve data with O(n) or worse characteristics. It presumably worked fine for a few years, then the sets of data being searched become non-trivial. Adding a system for indexing it made an immediate difference, but with close to a year of poor performance in the field while the old code was ripped out, updated, and tested; a better design up-front would have saved everyone a lot of headaches.

Sadly, I am one of those mathematically-troubled student whose taking-up Computer Science. I've barely passed all my math subjects (never failed one though) and I had a hard time in my Automata and Algorithms Complexity (Big o stuff) subjects. However, I aced all my programming subjects including Data Structures and Artificial Intelligence. I also aced all software development subjects. How important are those (Automota, Algorithms...., Mathematics) subjects in a Software Developers life? Am I doomed? Am I the only one who is stupid enough to take Computer Science when I know for a fact that I'm stupid in Math? :^)

I don't think it's all that important, it depends on exactly what you're working on though. It's important in games nowadays with all the 3D stuff going on and it can be important in business software that deals with money, tax and so on. For a lot (probably most) of software development work it isn't really necessary though.

Don't worry one bit, I'm exactly (probably even more) mathematically challenged than you are and I've done quite well in the field. Just don't expect to do any work in engineering fields or computer graphics fields unless you can find plug in algorithms and understand the concept of which tools are needed etc. Math is as close to irrelevant a skill for *most* programming these days as basket weaving.

As a bunch of people have said, unless you have your heart set on building software that requires math knowledge, don't worry about it. I have been a business applications programmer for a long time, and I do 'way more string handling than anything else. Just know what you don't know, and seek help with it.

I am mathematically challenged as well - this has not stopped me from being a successful DBA and writing image comparison, voice recognition etc applications. I have worked with Cambridge University mathematics graduates(who have 1sts!) and had no difficulty understanding complex algorithms they were designing and also, at times, surprised them with brilliant ideas :-\ Read my signature. Don't give up and most importantly find a way to find enjoyment in your work/study. Good Luck Guy ;)

Well, the same thing here. I figured I'd never need it, came across the need for all that good calculus stuff, popped open my old calculus book and it all came back. Just like riding a bike, once learned how, it pretty much sticks for the most part :rolleyes:

I do have a better grasp on certain aspects of calculus now, than when I was in college. Could have used what I figured out about it when taking the exams back then :sigh:

I too am not very good at math, but I learn what I need as I need it. I feel you have to want to learn.

Oooh yeah, my current project is cryptography. However, by reading Schenier's "Applied Cryptography" I was able to understand the underlying math (Finite Fields and stuff) and cryptographic primitives. My problem is I can't relate other math subjects like Integral Calculus to programming. :^)

I guess what I was really trying to say is that very seldom is the person who designs the user interface and the person who designs the library you use for a task going to be one in the same. Figure out what you are good at (or enjoy doing) and strive to be the best person on the planet in that subject.

He said "most," not "the highest paying" or the "most interesting" or even "the most challenging." Even if you use Laplace transforms in your work every day, most developers do not

:) I don't, nor do i really think a basic familiarity with maths is all that much more important than, say, a basic understanding of electronics, basic familiarity with recent usability studies, or a working knowledge of English grammar. That said, i don't understand the attitude that it's wise to just ignore information that isn't immediately useful; memorizing formulas may not buy you much, but learning when Googling them will save your ass is another matter. And basket weaving is both relaxing and good wrist exercise... :-\

not really. if you do any kind of business programming you at least have to know the order of operations in and out. at the bare bones minimum. and probably understanding percentage will be very helpful. ;P
