How do you create a subproblem in research?

Steps in Creating Subproblems

  1. Take the Problem Statement you created and isolate the possible subproblem areas, places where you can conduct research.
  2. Write a subproblem for each subproblem area, keeping in mind the same guidelines as used in writing the Problem Statement.

What is a subproblem in dynamic programming?

In computer science, a problem is said to have overlapping subproblems if the problem can be broken down into subproblems which are reused several times or a recursive algorithm for the problem solves the same subproblem over and over rather than always generating new subproblems.

What is Subproblem algorithm?

Here is the basic idea behind recursive algorithms: To solve a problem, solve a subproblem that is a smaller instance of the same problem, and then use the solution to that smaller instance to solve the original problem.

What is an example of a Subproblem?

A subproblem is a subparts of the main problem that is an integral part of the main problem. For example: Let’s say we are going to study the effect of a new drug, drug A, on lung cancer. This is a big project, so we can divide this main problem into several sub-problems.

How do you make a Subproblem?

Essayists take several approaches to presenting thesis subtopics or subproblems. Write the thesis sentence, and compose the subtopics into separate sentences, listing them from least important to most important. An example of this format: “The death penalty should be abolished.

What is the difference between Divide and conquer and dynamic programming?

Divide and Conquer works by dividing the problem into sub-problems, conquer each sub-problem recursively and combine these solutions. Dynamic Programming is a technique for solving problems with overlapping subproblems.

What is overlapping in DP?

A problem is said to have overlapping subproblems if the problem can be broken down into subproblems which are reused several times OR a recursive algorithm for the problem solves the same subproblem over and over rather than always generating new subproblems [2].

How Divide and conquer works?

Divide-and-conquer

  1. Divide the problem into a number of subproblems that are smaller instances of the same problem.
  2. Conquer the subproblems by solving them recursively. If they are small enough, solve the subproblems as base cases.
  3. Combine the solutions to the subproblems into the solution for the original problem.

What is the difference between Memoization and tabulation?

It is fast as the result of the previously solved sub-problems can be directly accessed from the table. It is slow because lots of recursive calls and return statements are required. In a tabulated version, all the entries must be filled one by one. In a memoized version, entries in the table are filled on demand.

How do you write a Subproblem?

Write the thesis sentence, and compose the subtopics into separate sentences, listing them from least important to most important. An example of this format: “The death penalty should be abolished. First, it costs taxpayers more money than confining prisoners to life in prison.

How do you identify problem and sub problem in research?

You can identify a research problem by reading recent research, theory and debates on your topic to find a gap in what is currently known about it. You might look for: A phenomenon or context that has not been closely studied. A contradiction between two or more perspectives.
