Detailed Description

Implementation of shared benchmark utilities and global configuration.

Provides:

• Global configuration: sample counts and thread count
• Result serialization: save benchmark results to CSV files
• Shared infrastructure for all benchmark types

Benchmark Components:

• Integration benchmarks: src/apps/benchmarks/integration_benchmarks.cpp Tests convergence and accuracy of MC, IS, MCMC methods
• PSO benchmarks: src/apps/benchmarks/pso_benchmarks.cpp Performance testing on sphere, Rastrigin, Rosenbrock functions
• GA benchmarks: src/apps/benchmarks/ga_benchmarks.cpp Genetic algorithm with population visualization

Sample Configuration:

• Logarithmic scale: 10k, 50k, 100k, 500k, 1M samples
• Enables convergence analysis: E[error] ∝ 1/√N

Function Documentation

saveResults()

void saveResults	(	const std::string &	filename,
		const std::vector< results > &	results,
		const std::string &	function_expr
	)

Export benchmark results to CSV file for analysis.

Save benchmark results to a CSV file.

Parameters

filename	Output CSV filename
results	Vector of benchmark results {n_samples, integration_result, duration_ms}
function_expr	String description of the integrated function

CSV Format:

• Header: Function description and column labels
• Each row: n_samples \t result \t duration_ms

Useful for:

• Plotting convergence curves: error vs sample count
• Computing empirical convergence rate
• Analyzing computational efficiency
• Comparing algorithm scalability
