Are they any helpful guidelines to describing what a Turing machine does if you already have the pseudo code for the algorithm?
I'm taking a course on complexity theory and it takes me a while to describe a Turing machine that decides or accepts some ...

I have a MySQL database with one particular MyISAM table of above 4 million rows. I update this table about once a week with about 2000 new rows. After updating, I then perform the following statement:
ALTER TABLE x ORDER BY PK DESC

The table is going to hold a small 36x72 Gravograph Roto Engraver...

There are four inputs, so won't have to recompile your code each time the decision table changes.
This means it is not a state machine, but only a truth table.
