Notes on Knapsack Problem Method

Overview

• Today's video focuses on the knapsack problem and strategies for solving it using Python.
• Introduction to a systematic strategy that can be applied to problem-solving.

Six Strategies for Solving Problems

1. State the Problem Clearly

   • Clearly articulate the problem you are facing.
   • Example: Knapsack problem is presented clearly.

2. Identify Input and Output

   • Specify what the inputs and outputs of the problem are.
   • Important to ensure clarity of what you're solving for.

3. Come Up with Example Inputs

   • Generate relevant example inputs and outputs to understand the problem better.
   • Ensure to cover all edge cases in your examples.

4. Implement a Solution

   • Write out the solution based on your understanding of the problem.
   • Test the solution using the example inputs.
   • Debug any issues that arise during testing.

5. Analyze Algorithm Complexity

   • Evaluate the efficiency of your solution in terms of time and space complexity.
   • Determine if the solution is optimal or if it requires improvements.

6. Apply the Right Technique to Overcome Efficiency Issues

   • If issues are found in step 5, revisit steps 3 to 6 to improve the solution.

Conclusion

• The six strategies provide a structured approach to problem-solving in programming, specifically for the knapsack problem.
• Encouragement to apply these strategies for easier problem-solving in the future.
