En la implementación parcialmente asíncrona, se propone reducir la frecuencia de la comunicación.
Para esto, cada hormiga realiza un cierto número de iteraciones del algoritmo secuencial,
independientemente de las otras hormigas. Solo después de estas iteraciones locales, se realiza una
sincronización global entre las hormigas. Entonces el master actualiza el nivel de feromonas y se
inicia el proceso de nuevo.
