Multi-Tape Turing Machines

Here we examine the Turing Machine variant where we are allowed to have any fixed number of tapes k at least 1. This seems more powerful than the standard model, as each of the tapes can move in any direction, and is fully independent (in a certain sense) of the other tapes. We show that this model is in fact equivalent to the standard model by putting all k tapes onto one with delimiters separating them. We then look at the details of how to carry out the simulation, and realize that there is a LOT of work to be done (number of states, new tape characters, etc.). But all of the work is finite, and can be done algorithmically. What is a Turing Machine? It is a state machine that has a set of states, input, tape alphabet, a start state, exactly one accept state, and exactly one reject state.
