comment Simplifying Fourier transform of a complicated function
The OP is doing a symbolic Fourier transform with FourierTransform. CUDAFourier does a discrete numerical transform like Fourier.

comment Extract a list of all built-in functions used in a notebook
@Öskå, from Leonid I would expect 2 pages of code which would not only find the functions but also automatically write the documentation for you :-)

@LaraJordan, ah okay. I only tested it with the simple example in the question.

FYI you can use the notation 1 <-> 2 for undirected edge.

comment A fast way to compare interval
Finally, I note that this solution relies on checking interval intersections only between adjacent list elements. So for example Tentative7[{{1, 10}, {2, 4}, {6, 8}}] returns {2} instead of {2, 3}. Is this the intended behaviour?

Secondly, your GIMQ function may be more succinctly written as GIMQ[{{a_, b_}, {c_, d_}}] := a <= c && b >= d

comment A fast way to compare interval
A couple of points - firstly please be aware that List is a terrible choice of variable name (as you used in LIP) because it is the symbol used by Mathematica as the head of lists. While it doesn't cause any problem here, it is generally good practice to avoid using built-in symbol names for your own variables.

comment A fast way to compare interval
I'm surprised you find Rasher's and my solutions so slow on a list of length 2000. For me they both take a fraction of a second. Perhaps your ListT is not a packed array. Try evaluating ListT = Developer`ToPackedArray[ListT]; and run the benchmarks again.

comment Building adjacency matrix from set data
In your example you have a unique symbol for each player and game. When you have thousands of players do you intend to use thousands of symbols? Does the actual data consist of hundreds of expressions like g1 = {p1, p3, p5} ?
