Benchmarking is essential in metaheuristic algorithms to evaluate and compare their performance using standardized test functions. It helps measure accuracy, stability, and efficiency before applying these algorithms to real-world problems.
Key concepts include:
-
Mean (Ī¼): Indicates the average performance of an algorithm.
-
Standard Deviation (Ļ): Measures result in variability across multiple runs, reflecting stability.
-
Benchmark Functions: Artificial test functions (e.g., Sphere, Rastrigin, Ackley) used to assess optimization algorithms.
By analyzing mean and standard deviation, researchers can determine how effective and reliable an algorithm is, ensuring better optimization results.
Steps to Calculate Mean & Standard Deviation:
- Generate random inputs within the function's domain.
- Evaluate the function at those points.
- Compute mean and standard deviation for function values.
ā Purpose of Benchmarking: Evaluate and compare algorithm performance before real-world application.
ā Benchmark Functions: Standardized test functions (e.g., Sphere, Rastrigin, Ackley) used for optimization testing.
ā Mean (Ī¼): Measures the average solution quality of an algorithm.
ā Standard Deviation (Ļ): Indicates the consistency and stability of the algorithmās performance.
ā Lower Mean (Minimization Problems): Shows better optimization performance.
ā Lower Standard Deviation: Implies more stable and reliable results across multiple runs.
ā Importance: Helps researchers improve algorithms by analyzing accuracy, convergence speed, and robustness.
