comment How to check if (u,v) and (v,u) edges are in a given directed graph
What have you tried so far? Where did you get stuck? EdgeList and MemberQ are helpful for a direct approach.

comment Error message when exporting plot as XLS file
It's not possible to export graphics to XLS. You can copy and paste the graphic to Excel if you like, but Export doesn't support graphics with XLS.

comment Unknown (internal?) function with `DSolve`
@ilian Taking it as a second constant, this solution appears to be correct. But in version 10.2.0, DSolve returns unevaluated instead of returning this solution. Is that a separate, new-in-10.2 bug?

comment How does LocationTest choose its “AutomaticTest”?
This question is tagged with bugs, but it's a very long post and after a quick skim it's not clear where/what the bug is. Can you clarify and give a summary of the bug at the top, for the benefit of other readers?

comment The module load only works for the first node, not all. Is there's a way to specify the full path to the math command when launching remote kernels
I wrote this little package for our cluster, which is definitely different enough from your cluster that it won't work there. But you might get some inspiration from it. I forgot the details, sorry, but I remember spending 1.5 days to figure out how to work around our cluster's undocumented idiosyncrasies (e.g. that ssh wont' work).

comment Is it possible to export equations from Mathematica to Corel with full Latex quality
Since v9.16, you can use the following with GhostScript: gs -o out.pdf -dNoOutputFonts -sDEVICE-pdfwrite in.pdf. This won't involve any conversions to EPS. It goes directly from PDF to PDF.

comment Match a variable name pattern
You have to convert to string, ToString, then use string matching functions. In general, try not to encode information meant to be read programmatically into variable names. It's error prone and considered bad style. It will also be very slow if you proceed to build something big with it ...
