    Browsing some mathematical packages like Sage and Maxima I found an interesting article on the complexity of R&D associated with algorithm development. It's a good read, but I don't know if I agree, I'm no Einstein but I can create complex algorithms and solve very complicated problems as if the answer was clearly written in the sky...

      The problem might be that you have not yet fully recognized the problem. :)

            Undergrad C.S. is basically a Math degree so I don't get where he suggests most software developers do not have the match experience necessary to develop complex algorithms. Seems like a paper written by someone who needs to get published more than anything profound or thought provoking.

                I checked where I went and an undergrad CS degree includes a lot of 1st and 2nd year math courses and a couple of 3rd year. That's it. Not even close to a math degree, which requires about 10 upper division math courses. Cheers, Drew.

                  mine was very math-intensive. but more importantly, there are a lot of programmers out there who didn't get CS degrees.

                    3 years of math out of 4 is fairly close considering most majors require 2 or 3 low level math courses like college algebra which isn't even high enough to count for CS, Engineering, and Math majors.

                      Yes, I was reading some of the comments by the readers. Seems there was a bit of banter about his assumptions. I did enjoy the one by: Boyd Moore, he makes some interesting observations about how easy it is for the human mind to work out the complexities of algorithms in physics etc. But I don't think he iis correct about the development of the ability until age 25 or so.

                        Not when it's most of 3rd and all of 4th year that's missing. 1st year is basically an extension of highschool algebra and basic calculus. 2nd year extends that and adds some new concepts. 3rd and 4th year take it to a whole new level of abstraction and complexity. Those are the years that provide the tools for solving very complex problems. All years are not created equal. Cheers, Drew.

                          I have to disagree with you completely. It's not a good read. The topic is interesting, his style could be better. When he gets to the meat, most of his readers have been drowned in vague blabber. He isn't clearly identifying what a "complex algorithm" is, and a paragraph title of "Complex algorithms are difficult" (well, duh!) doesn't help. Second, the point is not to create a complex algorithm. Rather, implementing an algorithm of given complexity in a way that it's provably correct, avoids all the pitfalls and still outperforms a dead pig. Frankly, your attitude towards complexity collides with your sig.

                              I don't consider what the company I work for does "complex algortihms" in the sense of the paper (paper? That's supposed to be a paper? Holy cow...) - largely it's clever application of standard signal processing. From my experiencem, the typical software developers does not have the experience to discuss these things at eye level with the engineers. And from some feeble attempts at a higher eh-duh-cajun I know that there are muhc harder problems.

                                  I don't mean to belittle a Math degree (math is hard work) but saying a CS grad doesn't have a math background, enough to plow through some complex algorithms is equally as unfair.

                                      Personally, I love the idea that Raymond spends his nights posting bad regexs to mailing lists under the pseudonym of Jane Smith. He'd be like a super hero, only more nerdy and less useful. [Trevel]

                                      Sadly, very few people pick that part up. Many of those people invoke Occam's Razor in the hopes that their "theory" will be given credibility. The same people should have invoked a psychiatrist... (No Dave, I'm not talking about you. :))

                                        Browsing some mathematical packages like Sage and Maxima I found an interesting article on the complexity of R&D associated with algorithm development. It's a good read, but I don't know if I agree, I'm no Einstein but I can create complex algorithms and solve very complicated problems as if the answer was clearly written in the sky...

                                          Is that grammatically correct? Shouldn't it be "you're right"? Just asking to know. :)

                                          Your right Rajesh* However, a lot of english speaking people do not care to do it right. (And I'm getting the feeling some americans don't even know how to do it right) *Place Sarcasm punctuation[^] here
