Deterministic turing machine
WebIn computational complexity theory, P, also known as PTIME or DTIME(n O(1)), is a fundamental complexity class.It contains all decision problems that can be solved by a … WebEvery nondeterministic Turing machine has an equivalent deterministic Turing Machine. PROOF IDEA Timeshare a deterministic TM to different branches of the nondeterministic computation! Try out all branches of the nondeterministic computation until an accepting configuration is reached on one branch. Otherwise the TM goes on forever.
