Don’t fully understand.You are not going to say the slower the better, do you? -deep_blue(BLUE); 2012-5-2 {55} (#7484066@0)

抛砖引玉一下。不算算法。如果不用DataView，自己做个快速排序的方法，那就是算法了。 -tjhong(以后再说); 2012-5-3 {763} (#7486233@0)
My point is not how to achieve it. Rather than, when we think our solution, do we try to use any math theory help our brainstorm? -deep_blue(BLUE); 2012-5-3 (#7487240@0)

in most cases simple arithmetics will do it so why bother to employ math? like this one is just sorting of a data set then compare the values with the neighbour rows. -newkid(newkid); 2012-5-3 (#7487663@0)

First of all, can you compare 100 thousands records by eyes? Second, in what criterion you define simple or complex. -deep_blue(BLUE); 2012-5-3 (#7487790@0)

it's simple and repeated,that's why we use computer. for me, "simple" means anything that can be solved by high school math -newkid(newkid); 2012-5-3 (#7487833@0)

前两年无意间读了codd 的那篇文章，然后看了些SQL的书籍，玩了一下as400，感觉真正的数学在数据库内部，然后对SQL就彻底没兴趣了。 -hhyang(哈哈羊); 2012-5-15 (#7518081@0)

Most IT people know math is base of IT. -deep_blue(BLUE); 2012-5-16 {547} (#7518464@0)

In terms R&D works in many fields, math is a tool, IT technologies, such as SQL, programming, are tools too (if needed). But math is used to help building model of R&D target rather than to help SQL or programming. -deep_blue(BLUE); 2012-5-16 (#7519853@0)

Yep, those tools tackle different problems. Process calculus/algebra sounds like the math for modelling concurrent systems, but writing real-time software with process calculus is very expensive.Software programming is such a complicated process that hasn't been fully understood. I'm afraid there won't be practical math theory for that in near future, otherwise a software tool may generate another software given user requirements as input. :-) -hhyang(哈哈羊); 2012-5-16 {256} (#7520179@0)

If it was true, I'm afraidit’s close to end of the world, like Terminator. -deep_blue(BLUE); 2012-5-16 {49} (#7520586@0)

Here is another simply question on matrix: graph can be represented as adjacency matrix. Now I understand but still don't understand why, the square of this matrix means the # of pathways between nodes.And more importantly, what about the matrix multiply the transpose of itself?

Thanks in advance! -renjl0810(Virtual Void); 2012-5-18 {99} (#7526028@0)
