comment How to program efficient undershoot/overshoot
I have mathematica 9, and I can't get your solution to work for any value of $k$ except for 0.4. I always get "stiff system" errors.

comment What is the purpose of Internal`LocalizedBlock?
@Mr.Wizard I guess I'm not familiar enough with Inherited`LocalizedBlock to provide a confident answer. Maybe I'll add it in the comments section.

comment Transform Root objects into Trigonometric expressions
@Vladimir I never really appreciated the possibility that roots of polynomials may be expressed as trig functions of rational multiples of $\pi$. Would you know where I can read more about this possibility?

Would it be feasible to search for the tulples using the GPU with its multitude of cores? e.g. via CUDALink or something like it?

comment Format Exp[] in output
@Mr.Wizard How about adding a LeafCount conditional to MakeBoxes as in: MakeBoxes[E^arg_, form_] := RowBox[{"Exp", "[", ToBoxes[arg, form], "]"}] /; LeafCount[arg] >= 10. Then E^Sqrt[x] formats differently than E^Sqrt[x^2+y^2]. Would you say this is objectionable?

comment Sum Over Multiple Indices part 2
The $f$ in your equation above appears to take one argument. The b[m,n,M] which is supposed to replace $f$ takes three arguments. Can you clarify the relationship between b and $f$?

comment why head Association cannot be replaced by head List
This is really interesting... is it possible to invent your own atomic object, and make your own functions that extract/manipulate their data?

comment Sum over multiple indices
@Eleven-Eleven I think you should as a new question, and include your code for f, and one of our (belisarius or my) codes for generating that sum.

comment Sum over multiple indices
@Eleven-Eleven I don't think either of us (belisarius or I) understand what you mean. Please ask a new question (and include what modifications/additions you made to our codes)

comment Sum over multiple indices
@Eleven-Eleven I don't understand what you mean by "I have replaced with what I needed and It seems that my sum is always 0". Exactly what did you replace??

@belisarius is there not a $1/k!$ missing?
