Methods of Algorithm – Independent Experimental” एक व्यापक विषय हो सकता है, इसलिए मैं इसे दो मुख्य भागों में स्पष्ट रूप से समझा रहा हूँ:


I. Algorithm Methods (Types/Approaches of Algorithms)

एल्गोरिदम डिज़ाइन के विभिन्न तरीकों (methods) को algorithmic paradigms कहा जाता है। ये सभी problem-solving approaches हैं।

1. Brute Force

2. Divide and Conquer

3. Greedy Method

4. Dynamic Programming (DP)

5. Backtracking

6. Branch and Bound

7. Randomized Algorithms


II. Independent Experimental Methods (Experimental Algorithm Analysis)

यह भाग algorithm performance testing और empirical study से जुड़ा होता है — जब आप अलग-अलग सिस्टम, डेटा या परिस्तिथियों में algorithm की व्यवहारिक जांच करते हैं।

Definition:

Experimental methods involve testing algorithms independent of theoretical analysis by running them on real or synthetic datasets.

Key Aspects:

  1. Input size variation:
    Performance under small, medium, and large inputs.

  2. Real vs Random Data:
    How it performs on worst-case, best-case, and average data.

  3. Platform Independence:
    Test on various hardware/software environments.

  4. Metrics measured:

    • Time (in seconds or milliseconds)

    • Space (memory usage)

    • Accuracy

    • Scalability


Steps in Experimental Methodology (Independent Testing)

Step Description
1⃣ Select algorithms to compare
2⃣ Choose datasets (real/synthetic/random)
3⃣ Run algorithms in a controlled environment
4⃣ Measure execution time, space, etc.
5⃣ Repeat for statistical significance
6⃣ Plot graphs, make conclusions

Tools Often Used:
