Detailed Description

Command-line interface for Monte Carlo integration and benchmarking.

Provides interactive access to six operational modes:

• Mode 1: Parser-based integration (muParserX)
• Mode 2: Hardcoded uniform Monte Carlo
• Mode 3: Metropolis-Hastings MCMC integration
• Mode 4: Polytope integration (Qhull)
• Mode 5: PSO optimization
• Mode 6: Genetic Algorithm

Supports seed control and OpenMP parallelization.
