Wikipedia has this to say: WebJan 31, 2024 · I am supposed to write a two-tape Turing machine (low level, all states, complete 7-tuple) to decide the following language: L = {w : w has exactly i a’s, exactly j b’s, and exactly k c’s, and k > i + j}, Σ = {a, b, c}. I then have to define a transition function δ appropriately for the machine and represent it as a table.

WebA deterministic Turing machine has a transition function that, for a given state and symbol under the tape head, specifies three things: the symbol to be written to the tape (it may be the same as the symbol currently in that position, or not even write at all, resulting in no practical change), WebA Turing machine is a hypothetical machine thought of by the mathematician Alan Turing in 1936.
