    <p>This node simulates a basic genetic algorithm. It takes a target string as input and evolves a population of random strings towards the target.</p>
    <p>The node has the following configuration options:</p>
    <ul>
        <li><b>Target</b>: The target string that the genetic algorithm will attempt to evolve towards.</li>
        <li><b>Population Size</b>: The size of the population in each generation.</li>
        <li><b>Mutation Rate</b>: The probability that a mutation will occur when creating a new generation.</li>
    </ul>
    <p>The node will output an object that includes the best individual string from each generation, its fitness, the generation number, and the original configuration parameters.</p>
