comment How can I stop DiscreteMarkovProcess[] from relabeling vertices?
@Peter you can initiate the subgraph by assigning zero transition probability to all the complimentary edges in $G/S$

comment Nest for large value of n
@thewanderer as Mark suggested one of the best papers on this topic is by Keith Briggs named "A precise calculation of the Feigenbaum constants Mathematics of Computation". You will find it here

comment How to find the index of a square matrix in Mathematica quickly?
@Szabolcs try testing your code with A={{1, 1, -1, 2}, {-1, 1, 0, 0}, {0, 1, -1, 2}, {1, 2, -1, 0}}. In my machine the kernel keeps on running....

comment Why the difference?
I guess he means this 1 + \!\( \*UnderoverscriptBox[\(\[Sum]\), \(n = 0\), \(\[Infinity]\)]\( \*UnderoverscriptBox[\(\[Sum]\), \(k = n\), \(\[Infinity]\)] \*FractionBox[\(1\), \(\((k + 1)\) \(k!\)\)]\)\). This by the way does not converge in Mathematica 9 and in place of 1 + e - Cosh[1] returns the input unchanged. The Sum version does converge to $\mathrm e$.

comment build and estimate a time series process
@Verbeia Not my ordinary neural net but all credit goes to proper keyword search in Google! However if you change AppendRows[a,b] with Join[a,b,2] and ZeorMatrix using ConstantArray you will be left with properly using the new version 9 ARMAProcess to replace your ARMAList. Then we can have a nice post here from you. Looking forward to it!

You are right! I randomly chose a distribution for this example..
