I have a question and I haven't been able to figure out the answer yet. I need to do the on-line simulation of a two-head tape Turing machine using single-head tape(s). I've found some online articles for the fact that one single-head tape doesn't suffice for this problem and the simulation should be done using two single-head tapes, but I haven't been able to present an accurate simulation of two-head TM using these single-head tapes. Are there any thoughts on how to do so? Thanks,
