In addition, it incorporated the domain knowledge into its initial population. This method increases greatly the efficiency of the algorithm and overcomes the problem of premature convergence of the simple genetic algorithm. This algorithm uses triangulated irregular network to model the virtual environment leading to lower in-core memory consumption.
