There are plenty of Chess AI's around, and evidently some are good enough to beat some of the world's greatest players.
I've heard that many attempts have been made to write successful AI's for the board game Go, but so far nothing has been conceived beyond average amateur level.
Could it be that the task of mathematic... | 0 | 1 | 0 | 0 | 0 | 0 |

I am looking for a way to convert any number to a percentage in the following way:
1.00 is 50%
numbers below 1.00 approach 0% logarithmically
numbers above 1.00 approach 100% logarithmically.
x > 0. So y needs to approach 0 as x becomes infinitely small on the positive side.
I'm sure this is simple to do, but I ... | 0 | 0 | 0 | 0 | 1 | 0 |
I've 3 .jsp files. index.jsp and sqrtcalculator.jsp and error.jsp.
In index.jsp there's a text field and a button. In sqrtcalculator.jps there's the, well, calculator.
Now, when I leave the field empty and press the button, an expection is called, because the field is empty. And I can then reroute to an individual erro... | 0 | 0 | 0 | 0 | 1 | 0 |

I have to do a final project for my computational linguistics class. We've been using OCaml the entire time, but I also have familiarity with Java. We've studied morphology, FSMs, collecting parse trees, CYK parsing, tries, pushdown automata, regular expressions, formal language theory, some semantics, etc.

Is there a lowest common denominator format for multidimensional images or matrices analogous to netpbm/netpgm for 2d images?
How would you use protocol buffers to define a 3d image or matrix of 16 bit unsigned numbers?
Why didn't the netpbm people allow more dimensions in the row, column line?

I am trying to check the location of a point(px, py) on 2D graph in relation to a line segment (lx1, ly1) (lx2, ly2), using logic of North South East West directions. The logic I have implemented is to draw a perpendicular on the line segment from the point.
if perpendicular is on line that means its south.

What would be a fast way to implent this osscilation function.
A signature would look like this:
public static double Calculate(UInt64 currentCounter, uint duration, uint inDuration, uint outDuration)
And the result should be a double that as currentCounter advances, ossciates between 0 and 1. The osscialtion speed is... | 0 | 0 | 0 | 0 | 1 | 0 |
I have a double which is:
double mydouble = 10;
and I want 10^12, so 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10. I tried
double newDouble = pow(10, 12);
and it returns me in NSLog: pow=-1.991886
makes not much sense... I think pow isn't my friend right?

I'm interested in implementing an algorithm on the GPU using HLSL, but one of my main concerns is that I would like a variable level of precision. Are there techniques out there to emulate 64bit precision and higher that could be implemented on the GPU.
Thanks!

How can i generate dynamically this array.
var posX:Array = [0,-20,20,-40,0,40,-60,-20,20,60,-80,-40,0,40,80,-100,-60,-20,20,60,100]
The numbers in the array refer to the x position of the object. I use it to place objects in triangular formation.
0
-20 20
-40 0 40
-60 -20 20 60 etc
Thank you in advance

I'm trying to write a function that can calculate revenue at different tiered levels... For example you sell $10000 worth of widgets. Any earnings from $1 - $999 we take 50%, $1000 - $4999 we take 25%, $5000 - $9999 we take 10%, $10000 - $19999 5%.
The percentage is not taken based on the final value. So if you earned... | 0 | 0 | 0 | 0 | 1 | 0 |
In javascript, I am trying to draw a line that is at an angle that is user defined.
Basically, I have a point (x,y) and an angle to create the next point at. The length of the line need to be 10px.
