What is an intractable problem in computer limitations and can give the example?

An intractable problem is one for which there is an algorithm that produces a solution - but the algorithm does not produce results in a reasonable amount of time. Intractable problems have a large time complexity. The Travelling Salesman Problem is an example of an intractable problem.

WHAT IS THE DIFFERENT algorithm of advantage and amp disadvantage?

Different algorithms do different things, so it makes no sense to compare them. For example, the accumulate algorithm is an algorithm which performs the same operation upon every element of a container, whereas a sorting algorithm sorts the elements of a container. Each specific algorithm requires a different set of concepts. An accumulate algorithm requires a data sequence with at least forward iteration and elements which support the operation to be performed, whereas a sorting algorithm generally requires random access iterators and elements that support a given comparison operation (such as the less-than operator).Even if two algorithms have the exact same time and space complexities, it does not follow that both will complete the task in the same time. For instance, the accumulate algorithm is a linear algorithm with a time-complexity of O(n) regardless of which operation is being performed. However, the complexity of the operation itself can greatly affect the actual time taken, even when the operations have exactly the same time-complexity. For instance, if we use the accumulate algorithm in its default form (to sum all the elements in a data sequence), the operation itself has a constant-time complexity of O(1). If we choose another operation, such as scaling each element and summing their products, it will take much longer to complete the algorithm (possibly twice as long) even though the operation itself has the exact same time-complexity, O(1).Consider the time-complexity of adding one value to another:a += bThis has to be a constant-time operation because the actual values of a and b have no effect upon the time taken to produce a result in a. 0 += 0 takes exactly the same number of CPU cycles as 42 += 1000000.Now consider the operation to scale and sum:a += b * 42Here, 42 is the scalar. This also has to be a constant-time operation, but it will take longer to physically perform this operation compared to the previous one because there are more individual operations being performed (roughly twice as many).The only way to compare algorithms is to compare those that achieve exactly the same goal but do so in different ways. Only then does comparing their respective time-complexity make any sense. Even so, time-complexity is merely an indication of performance so two sorting algorithms with the exact same time-complexity could have very different runtime performance (it depends on the number and type of operations being performed upon each iteration of the algorithm). Only real-world performance testing can actually determine which algorithm gives the best performance on average.With sorting algorithms, we often find one algorithm ideally suited to sorting small sequences (such as heap sort) and others ideally suited to larger sets (such as merge sort). Combining the two to create a hybrid algorithm would give us the best of both worlds.


What is meant by the complexity of an algorithm?

Complexity of an algorithm is the study of how long a program will take to run, depending on the size of its input & long of loops made inside the codeSpecifically, the complexity of an algorithm is a measure of how long it takes to complete (give an answer) relative to increasing sizes of input data. Thus, complexity is not concerned with how long it took the algorithm to run using X amount of data. Rather, it is concerned with the relationship in runtime when using X amount of data, 2X amounts of data, 10X amounts of data, etc. While complexity usually refers to execution time, it can also be applied to other resource usage (for example, memory allocation). In all cases, complexity is concerned with the relationship between the rate of increase in resource consumption and the rate of increase of the size of the data set being worked on.Complexity is closely related to the concepts of scalingand efficiency, but is NOT an exact equivalence to either.

Can you give algorithm for my programs?

That's not our job.Unless your programs are trivial, the algorithm is likely to be too complicated to explain here, and if they are trivial, then... well, then they're trivial, and you should be able to figure them out yourself.
