Algorithms

An algorithm is a self-contained step-by-step set of operations to be performed. Algorithms exist that perform calculation, data processing, and automated reasoning. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.

Imagine you have a dataset of rowers. You have X variables such as weight, benchpress, deadlift, squat, nutrition, etc. You also have each rower's lap time.

Now, let's say for a given rower, you want to optimize her lap time, but you can only train along ONE DIMENSION. How would you identify the best attribute to optimize?

I thought about a grid search, but that seems awful. Which family of machine learning algorithms would be best for this type of problem, and how would you attack it?

Thanks a million!

I have question about the GA application in an intrusion detection, what programming language can be applied for this type of problem.

I got a requirement from my client that he wishes to encrypt/ password protect some of the documents, before sending over to another user in another regional office.

By not writing the password into the email body.

How can the user in another regional office knows the password to decrypt/ open the protected documents?

What approach should be adopted? Is there any standard/ algorithm I can refer to? But we prefer not to use any 3rd party software/ utility.

Thank you.

Hi
I am working on GIS applications and found the slope algorith in the net :

ftp://ftp.ecn.purdue.edu/jshan/86/help/html/gmd/slope_percent.htm

attached is an example I used to apply the above algorithm for calculating slopes from a DEM. I am not good in math so I got two results.
Can you help me please . I got 73, -33, 56.648 and I do not how to do the arctan.
