Turing machine | Computational complexity theory
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. will be designed to compute a log-space computable function (where is the alphabet of both the input and output tapes). If is executed with on its input tape, when the machine halts, it will have remaining on its output tape. A language is said to be log-space reducible to a language if there exists a log-space computable function that will convert an input from problem into an input to problem in such a way that . This seems like a rather convoluted idea, but it has two useful properties that are desirable for a reduction: 1. * The property of transitivity holds. (A reduces to B and B reduces to C implies A reduces to C). 2. * If A reduces to B, and B is in L, then we know A is in L. Transitivity holds because it is possible to feed the output tape of one reducer (A→B) to another (B→C). At first glance, this seems incorrect because the A→C reducer needs to store the output tape from the A→B reducer onto the work tape in order to feed it into the B→C reducer, but this is not true. Each time the B→C reducer needs to access its input tape, the A→C reducer can re-run the A→B reducer, and so the output of the A→B reducer never needs to be stored entirely at once. (Wikipedia).
Isolating a logarithm and using the power rule to solve
👉 Learn how to solve logarithmic equations. Logarithmic equations are equations with logarithms in them. To solve a logarithmic equation, we first isolate the logarithm part of the equation. After we have isolated the logarithm part of the equation, we then get rid of the logarithm. This i

Abstract : Recall that normality is a elementary form of randomness: an infinite word is normal to a given alphabet if all blocks of symbols of the same length occur in the word with the same asymptotic frequency. We consider a notion of independence on pairs of infinite words formalising
