comment Hardware required to perform large symbolic calculations
For symbolic computations I would have thought that clock speed was a stronger consideration than number of cores?

comment Summing Normal random variables
This is incorrect. The OP wanted the PDF of the sum of two random variables, not the sum of two PDFs.

It seems a teeny bit faster to use Infinity in place of Max[#]

comment How can I produce a list of solutions for a function which is updated with updated variables using for loop?
I have done a major edit to your question to clarify and simplify it. I believe it is now answerable so will vote for it to be reopened.

comment How can I produce a list of solutions for a function which is updated with updated variables using for loop?
As for actually answering the question, it would help a lot if you stated what output you are expecting. Do you just need the sum of all the solutions for X? Or perhaps a list of {1st solution, 1st + 2nd solution, 1st + 2nd + 3rd, etc...}

It would have been better to edit the original question to address why that answer was no good for you. Editing bumps the question - giving it more visibility - and it isn't considered rude, whereas deleting and reposting when people have already invested effort in trying to help you is rude.

comment Why do I get Floor and Ceiling in my output despite my assumptions
@bills This is strange. Surely using the Assumptions option to Sum, setting the global $Assumptions and using Assuming should all have the same effect?

comment How to speed up band matrix-matrix multiplication?
What version are you using? With version 10 on Windows I get 1.75 secs for a.u and 1.2 secs for a2.u (but with an added overhead of 2.4 secs to calculate part)

comment Manipulate Parametric Plot
Check the documentation for ParametricPlot - the coordinates need to be in a list: ParametricPlot[{fx, fy}, {u, umin, umax}]

comment Coloring edges of a graph according to their weight?
Nice. I didn't realise you could use patterns in EdgeStyle. FYI you can use <-> for a slightly more readable UndirectedEdge.

comment CPU usage remains at 13% even after I quit the kernel
Mathematica.exe is the front end process, not the kernel (which is MathKernel.exe). It does sound like a bug though - does the CPU usage continue even after all notebooks are closed?

Good question. I was sure that one of vor["Properties"] would hold the answer but no luck...

comment On the order of rules specification
As I understand it, a pattern with a condition attached is considered more specific than one without, but in general there is no way to say that one condition test is more specific than another. How would you order x_/;blackbox1[x] and x_/;blackbox2[x]?
