/**
 * @file main.cpp
 * @brief Main entry point for the puzzle solver application.
 * 
 * This file contains the main function which initializes the puzzle solver,
 * reads input, generates an initial population, and evolves the population
 * over a specified number of generations.
 * 
 * @details
 * The program expects an optional command-line argument:
 * - `-v` : Enables verbose output.
 * 
 * The user is prompted to input the population size and the number of generations.
 * The program then measures the time taken to evolve the population and outputs
 * the elapsed time.
 * 
 * @param argc Number of command-line arguments.
 * @param argv Array of command-line arguments.
 * @return int Exit status of the program.
