Computer as a Model of Computation in Problem Solving

A computer acts as a model of computation by taking a problem, processing the given data according to a set of instructions, and producing the required result.

The process can be explained in the following six simple steps:

1. Problem Definition

Clearly identify what problem needs to be solved and what result is expected.

2. Input

The computer accepts the required data from the user or another source.

3. Algorithm

A step-by-step procedure is designed to tell the computer how to solve the problem.

4. Processing

The computer executes the instructions of the algorithm and performs the required calculations or operations.

5. Output

The computer produces and displays the result obtained from processing the input.

6. Evaluation

The result is checked to determine whether it correctly solves the problem. If necessary, the algorithm or program is modified.

PadLocking

Padlocking Problem – Brute Force Method The padlocking problem is a simple real-life example that can be used to explain the Brute Force method of problem solving . The problem is: A combination padlock has several number dials. The correct combination is unknown. Find the combination that opens the lock by systematically trying all possible combinations. For classroom teaching, we can use a small hypothetical 3-digit padlock . 1. Understanding the Problem Suppose we have a padlock with 3 dials , and each dial contains digits from 0 to 9 . For example: Dial 1 Dial 2 Dial 3 ↓ ↓ ↓ 0 0 0 Each dial has 10 possible values . Therefore, the total number of possible combinations is: 10 × 10 × 10 = 10 3 = 1000 10 \times 10 \times 10 = 10^3 = 1000 So there are 1,000 possible combinations , ranging from: 000 001 002 003 ... 997 998 999 2. Brute Force Approach We don't have any information about the correct combination. Theref...
