What is space time trade off?

In computer science, a space-time or time-memory tradeoff is a way of solving a problem or calculation in less time by using more storage space (or memory), or by solving a problem in very little space by spending a long time.

What are the examples of time space trade off?

Types of Space-Time Trade-off

• Compressed or Uncompressed data.
• Re Rendering or Stored images.
• Smaller code or loop unrolling.
• Lookup tables or Recalculation.

What is the time space tradeoff principle give an example?

A classic example of a space/time tradeoff is the lookup table. A lookup table pre-stores the value of a function that would otherwise be computed each time it is needed. For example, 12! is the greatest value for the factorial function that can be stored in a 32-bit int variable.

What is the importance of space and time trade tradeoffs?

Space-time trade-offs are prevalent in biology, cryptography and dynamic programming. If your problem is taking a long time but not much memory, a space time trade-off would let you use more memory and solve the problem more quickly. Larger code size can be used to increase program speed when using loop unwinding.

Which is more important space or time complexity?

Space complexity is usually referred to as the amount of memory consumed by the algorithm. It is composed of two different spaces; Auxiliary space and Input space. The factor of time is usually more important than that of space.

What is trade-off in programming?

A trade-off (or tradeoff) is a situational decision that involves diminishing or losing one quality, quantity, or property of a set or design in return for gains in other aspects. In simple terms, a tradeoff is where one thing increases, and another must decrease.

Why do trade-offs exist?

Lesson Summary A trade-off involves a sacrifice that must be made to obtain a desired product or experience. Understanding the trade-off for every decision you make helps ensure that you are using your resources (whether it’s time, money or energy) wisely.

Why do people face trade-off?

To get something you want, you have to give up something else you want. Scarce resources. Think of allocating your time or money. Societies face a tradeoff between more consumer goods (low taxes) and more public goods (defense, social programs).
