Algorithms which have exponential time complexity grow much faster than polynomial algorithms. The difference you are probably looking for happens to be where the variable is in the equation that expresses the run time. Equations that show a polynomial time complexity have variables in the bases of their terms. Examples: n^3 + 2n^2 + 1. Notice n is in the base, NOT the exponent.

In exponential equations, the variable is in the exponent. Examples: 2^n.

As said before, exponential time grows much faster. If n is equal to 1000 (a reasonable input for an algorithm), then notice 1000^3 is 1 billion, and 2^1000 is simply huge!

For a reference, there are about 2^80 hydrogen atoms in the sun, this is much more than 1 billion.

Is the time complexity of the algorithm polynomial or superpolynomial?

The time complexity of the algorithm is superpolynomial.


What is the complexity of the algorithm in terms of time and space when solving a problem with an exponential space requirement?

The complexity of the algorithm refers to how much time and space it needs to solve a problem. When dealing with a problem that has an exponential space requirement, the algorithm's complexity will also be exponential, meaning it will take a lot of time and memory to solve the problem.


How do polynomial time vs. exponential time algorithms compare?

An algorithm that completes in "polynomial time" is faster to solve than an algorithm that completes in "exponential time" in most of the important cases where it needs to be solved. An algorithm that completes in "polynomial time" the time to solve is always determinable by a polynomial equation (e.g. x^2, x^4+7*x^3+12*x^2+x+19, x^8392). An algorithm that completes in "exponential time" the time to solve can only be determined an exponential equation (e.g. 2^x, e^x, 10^x, 982301^x). Exponential equations give larger value answers than polynomial equations after a certain input value and then increase progressively faster. This makes "exponential time" algorithms take much longer than "polynomial time" algorithms to solve, often making many of them effectively unsolvable for certain cases. Many of the most important algorithms needed to solve real world problems are "exponential time" algorithms.

Differentiate between polynomial algorithm and exponential algorithm?

Do you mean, "the difference between an algorithm that runs in polynomial time, and one that runs in exponential time".First a real quick review. A polynomial is any equation of the formy = cmxm + ... + c2x2 + c1x + c0 ,where ci are constantsAn exponential function is something of the formy = cxThese functions grow much faster than any polynomial function.So, if T(n) describes the runtime of an algorithm as a function of whatever (# of inputs, size of input, etc.)., and T(n) can be bound above by any polynomic function, then we say that algorithm runs in polynomial time.If it can't be bound above by a polynomial function, but can be bound above by an exponential function, we say it runs in exponential time.Note how ugly an exponential algorithm is. By adding one more input, we roughly double (or triple, whatever c is) the run-time.


What is the time complexity of backtracking algorithms?

The time complexity of backtracking algorithms is typically exponential, meaning the runtime grows rapidly as the input size increases.


Is 1 divided by x exponential?

no it is a polynomial. exponential is a number to the x power (3^x)


What is polynomial complexity?

That means that the running time of a program is proportional to some power of the input size.
