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 ...
In computational complexity theory, SL (Symmetric Logspace or Sym-L) is the complexity class of problems log-space reducible to USTCON (undirected s-t connectivity), which is the problem of determining whether there exists a path between two vertices in an undirected graph, otherwise described as the problem of determining whether two vertices are in the same connected component.
Insufficient storage space in system. File unavailable (e.g., file busy). 500 Series: Syntax error, command unrecognized and the requested action did not take place ...
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]
NL is a generalization of L, the class for logspace problems on a deterministic Turing machine. Since any deterministic Turing machine is also a nondeterministic Turing machine, we have that L is contained in NL. NL can be formally defined in terms of the computational resource nondeterministic space (or NSPACE) as NL = NSPACE(log n).
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.

They may also include a display for providing location and speed information to the user. GPS receivers may include an input for differential corrections, using the RTCM SC-104 format. This is typically in the form of an RS-232 port at 4,800 bit/s speed. Data is actually sent at a much lower rate, which limits the accuracy of the signal sent ...
