Tally oracles are a specific type of oracle used in computational complexity theory where the input consists of non-negative integers represented in unary format. They are important because they highlight the limitations of relativization, showing that there are certain complexity classes that behave differently when given access to such oracles compared to traditional oracles. Tally oracles help illustrate the boundaries of what can be computed with additional information, particularly within the context of decision problems and their complexity classifications.
congrats on reading the definition of Tally Oracles. now let's actually learn it.
