FL (complexity)

In computational complexity theory, FL (Function Logarithmic) refers to the class of functions that can be computed by a logarithmic space-bounded Turing machine. More specifically, FL is often used to denote functions that can be decided with logarithmic space in a deterministic way. ### Key Points about FL: - **Logarithmic Space**: A Turing machine is said to operate in logarithmic space if the amount of memory it uses is proportional to the logarithm of the input size.
