comment Sequential System of Equations
I think you need to define your problem better, in the mathematical sense. Is G(t) a function that takes a state of the system D(t) at time t to the state at time t+1? Is G(t) known as a function of time? Is time a discrete variable (as your diagram seems to suggest) or is it continuous? In order to program effectively, in Mathematica or anything else, you (and the community here, if they are to help you) need to understand precisely the problem that you want to solve.

comment Limit the number of processors used by ParallelTable?
@GordonCoale This is a Mathematica script, which will run with no graphical interface.

comment Match opening and closing parentheses?
This is a particular case of mathematica.stackexchange.com/q/78083/534. I don't think it's a duplicate, since the particular case can probably be solved more efficiently than the general one.

@DanyloDubinin Can you post an answer and explain a little what you're doing?

comment Export as Table with alignment?
@YvesKlett I just found a way to do it and posted an answer. However, ideally I would like to specify different alignments for different columns.

comment Export as Table with alignment?
@YvesKlett I added an example. How bad the misalignment looks depends on the tab size, of course.

comment How to get only the directories (not the files) inside the current directory?
@Kuba That's not more general, it's a different problem. Here I want to list only the directories inside the current one, without going recursively into deeper levels.

@Kuba I just discovered that. Thanks.

See edit for my system version.

comment How to stop a .sh script that calls multiple Mathematica scripts?
I am using a script because I am running Mathematica stuff as well as calling other programs, all together. I want to stop it mostly for debugging processes (the usual start, stop, repair, restart routine).

comment Intensive test parallel computation?
@OleksandrR. You can assume that it is a single multi-core PC. I don't have a lot of details since it is a remote cluster.

comment Intensive test parallel computation?
@DumpsterDoofus The downside with that example is that you don't know the results before hand.

comment Is there a LogBeta function like the LogGamma?
What about the logarithm of the incomplete Beta function? That can't be reduced to LogGammas. Just asking cause I had a similar underflow/overflow problem using Beta or BetaRegularized to compute incomplete Beta values.

comment How to exclude the diagonal in a MatrixPlot?
Thanks. Let me just point out that I ended up using BarLegend instead of plotting a legend using MatrixPlot.

comment FindGraphCommunities method options?
@Szabolcs I sent them an email. If I receive a reply I'll post it here. In the meantime, and in case I don't receive any reply from Wolfram, maybe people in this forum with experience using FindGraphCommunitites may want to share what they have learned.

comment Split graph into independent maximal cliques?
I don't expect a specific result. I know there are several ways to do the partition I want. What I want is something similar to what FindGraphCommunitites does, but only choosing communities that are cliques. I hope it's clearer now.

comment How to exclude the diagonal in a MatrixPlot?
This paints the diagonal elements using the color in the gradient scale corresponding to the minimum matrix element. That's not what I want. I want the diagonal elements to receive a separate color, unrelated to the color used for non-diagonal elements. Otherwise it might give the impression that diagonal elements equal the minimum matrix elements.

comment Split graph into independent maximal cliques?
@DavidG.Stork A trivial partition into cliques that works for any graph is a partition into subsets containing single vertices. Of course, that's not what I want, but it illustrates that a partition with the conditions I seek always exists. It's only a matter of choosing the most appropriate.
