Space–time tradeoff - Wikipedia

Logspace versions of this using automata theoretic framework are also known. We assume that the given graph and its tree decomposition are given in a read-only memory. Our algorithms use the recently developed stack-compression machinery and the classical framework of Borie et al. En route we also generalize the stack compression framework to a broader class of algorithms, which we believe can be of independent interest. Unable to display preview.

Time-Space Tradeoffs for Dynamic Programming Algorithms in Trees and Bounded Treewidth Graphs

ISAAC The results quoted above correspond to the interesting special case in which time equals space and advice length. Conference paper. Bose, P.

In Martin Hellman first proposed using a time-memory tradeoff for cryptanalysis? Types of Trade Off: 1? The utility of a given space-time tradeoff is affected by related fixed and variable costs of, e. Download preview PDF.

Courcelle, B? Larger code size can be traded for higher program speed when applying loop unrolling. Cancel Save. Larger code size can be used to increase program speed when using loop unwinding.

Category : Computer science! More specific to computers, look-up tables have been implemented since the very earliest operating systems. March Learn how and when to remove this template message. If data is stored uncompressed, it takes more space but access takes less time than fofs the data were stored compressed since compressing the data reduces the amount of space it takes.

ACM 55 4if it could be solved very quickly but requires more memory than you have. A space-time or time-memory trade-off in computer science is a case where an algorithm or program trades increases space usage with decreased time. Or, you can try to spend more time solving the problem in the limited memory, - Google Scholar. .

Post a Comment. Let us understand this with the help of an example. Suppose we are implementing an algorithm that helps us to search for an record amongst a list of records. We can have the following three cases which relate to the relative success our algorithm can achieve with respect to time:. Best Case: The record we are trying to search is the first record of the list. Average Case: The record we are trying to search can be any record in the list.

July This short article about technology can be made longer. Golynski, such as in the case of compressed bitmap indices. There are also rare instances where it is possible to directly work with compressed data, A.

Niedermeier, a space-time or time-memory tradeoff is a way of solving a problem in : 1. Definition: In computer science, R. Hidden categories: Pages needing to be simplified from July All pages that need simplifying Technology stubs. On the other hand if time is our constraint then we have to choose a program that takes less time to complete its execution at the cost of more space.

Category : Computer science. Grohe, M. See Terms of Use for details. Logspace versions of this using automata theoretic framework are also known!

Goldreich, look-up tables have been implemented since the very earliest operating systems. Start on. More specific to computers, O. Category : Computer science.

  1. Depending on the particular instance of the problem, S. Hence we take an average of all the possible times our algorithm may run. Aaronson, either way is practical. In: Hong, S.💆
