L is a subclass of NL, which is the class of languages decidable in logarithmic space on a nondeterministic Turing machine.A problem in NL may be transformed into a problem of reachability in a directed graph representing states and state transitions of the nondeterministic machine, and the logarithmic space bound implies that this graph has a polynomial number of vertices and edges, from ...
The constant 1/3 is arbitrary; any x with 0 ≤ x < 1/2 would suffice. It turns out that C = NL . Notice that C , unlike its deterministic counterpart L , is not limited to polynomial time, because although it has a polynomial number of configurations it can use randomness to escape an infinite loop.
In computational complexity theory, a log-space computable function is a function : that requires only () memory to be computed (this restriction does not apply to the size of the output). The computation is generally done by means of a log-space transducer .
In computational complexity theory, a log space transducer (LST) is a type of Turing machine used for log-space reductions. A log space transducer, , has three tapes: A read-only input tape. A read/write work tape (bounded to at most () symbols). A write-only, write-once output tape.

In computational complexity theory, a log-space reduction is a reduction computable by a deterministic Turing machine using logarithmic space. Conceptually, this means it can keep a constant number of pointers into the input, along with a logarithmic number of fixed-size integers . [ 1 ]
To fix this, the user should close some programs (to free swap file usage) and delete some files (normally temporary files, or other files after they have been backed up), or get a bigger hard drive. Out of memory
If the reference name includes characters other than standard English alphabet and numerals, then those characters will be dot encoded. That is, the characters will be converted to ASCII hexadecimal and shown with a period before them.
