摘要翻译：
高效自然进化策略(eNES)是传统进化算法的一种新选择，它利用自然梯度来适应变异分布。与以往基于自然梯度的进化算法不同，eNES采用快速算法计算精确Fisher信息矩阵的逆，从而提高了进化梯度估计的鲁棒性和性能，即使在高维环境下也是如此。eNES的其他新方面包括最佳适应度基线和重要性混合（一种用很少的适应度评估更新总体的程序）。该算法在单峰和多峰基准上都产生了竞争性的结果。

英文摘要：
Efficient Natural Evolution Strategies (eNES) is a novel alternative to conventional evolutionary algorithms, using the natural gradient to adapt the mutation distribution. Unlike previous methods based on natural gradients, eNES uses a fast algorithm to calculate the inverse of the exact Fisher information matrix, thus increasing both robustness and performance of its evolution gradient estimation, even in higher dimensions. Additional novel aspects of eNES include optimal fitness baselines and importance mixing (a procedure for updating the population with very few fitness evaluations). The algorithm yields competitive results on both unimodal and multimodal benchmarks.
