Ways of Applying
There are three main ways of applying the transform and conquer technique:
1. Instance simplification:
In the transform and conquer technique, the problem is simplified by transforming it into a more manageable form. This can be done by reducing the size of the problem, breaking it down into smaller pieces, or changing the structure of the problem. This technique can be used to simplify problems that are too large to solve using traditional methods. The instance simplification technique is a process of reducing the size of a problem instance by removing irrelevant or redundant information. The goal of this technique is to make the problem instance easier to solve without changing the problem itself.
To learn more about this refer to the article on “Instance Simplification in Transform and Conquer Technique“.
2. Problem reduction:
Problem reduction is a technique used in the transform and conquer technique. The idea behind problem reduction is to transform the given problem into another problem that is easier to solve. This can be done by transforming the problem into another form, or by using a heuristic to find a solution.
For example, consider the problem of finding the shortest path between two nodes in a graph. One way to solve this problem is to reduce it to the problem of finding the shortest path between two nodes in a tree. This can be done by finding the minimum spanning tree of the graph and then finding the shortest path between the two nodes in the tree.
3. Representation change:
In the transform and conquer technique, the representation change is used to simplify the problem and improve the efficiency of the algorithm. The main idea behind this technique is to change the representation of the data so that it can be solved more easily. This can be done by changing the input data or the output data.
In the representation change data is first transformed into a form that is more convenient for the subsequent analysis. This can involve, converting the data into a tabular form, or aggregating the data into groups. Once the data has been transformed, it is then passed to a sub-routine or function that performs the required analysis.

Transform and Conquer Technique
The Transform and conquer technique is a way of solving problems by breaking them down into smaller subproblems, solving the smaller subproblems, and then combining the solutions to the subproblems to solve the original problem. This technique can be used to solve problems in many different areas, including mathematics, computer science, and engineering. This technique is often used when the original problem is too difficult to solve directly, or when it is easier to solve the smaller sub-problems.
