If two states are identical, they can be merged; if they're not, they can't. There's always going to be a point where no more states can be merged: if that wasn't the case, every Turing machine would have only one state, and there aren't many different one-state machines! – David Richerby. bjt load line analysisA Turing machine is a mathematical model of computation describing an abstract machine that manipulates symbols on a strip of tape according to a table of rules.
