Shouldn't each instance of "function" be changed to "Function" above?

comment A better simplification function
It would be good if SuperFullSimplify had a MaxTime option. Once the maximum time has passed it should return the best answer it found so far. Also, it seems no ComplexityFuntion is full proof. There will always be cases where the expression deemed least complex isn't the one you like best. It would be good if we could get the 3,4,5 etc expressions have the lowest complexity based on the specified ComplexityFuntion.

comment What Mathematica features and idioms have $n^2$ complexity or worse
@Jacob Akkerboom you can change the question to anything you like. Also, I would very much like to have a list of coding practices that are shoe to lead to slow programs in Mathematica.

comment A better simplification function
I saw VOISimplify when it was posted in MathGroup years ago. Ever since, I have wanted WRI to make FullSimplify do this when the LeafCount and number of variables is not too large.

comment How to speed up solution of system of recurrence equations
These equations are unusual because the values of U, V, and Z depend only on future values of U, V and Z. In any case the right tool for this problem is the RecurrenceTable feature documented at reference.wolfram.com/language/ref/…

comment A problem about fixed point iteration theory
I didn't intend to say you are wrong. However, one who does not read carefully might think precision always decreases as computation continues. I wanted to make it clear that isn't always the case.

comment A problem about fixed point iteration theory
From the explanation above you might conclude that the result of a computation always has less precision than the precision than the numbers used in the computation. However, you increase precision in the next two examples. ------- In[1]:= x=SetPrecision[6.2,4.0]; Precision[Erf[x]] Out[2]= 19.9801 In[3]:= Precision[2+(x-62/10-10^-30)^6] Out[3]=19.5467
