In the Gutenberg-Richter relation that describes the frequency-magnitude distribution of earthquakes, the b value represents the distribution's slope. Since b values can be used for mapping the dynamic response of earthquake source, methodologies for calculating robust b values are of great importance. Although nowadays software which is meant for statistical analysis of earthquake data can determine b values with high accuracy, in occasions where catalogs that contain small number of earthquake events, the produced results are not satisfactory. In this paper we present a new self-optimized algorithm for a more efficient calculation of the b value. The algorithm's results are compared with two widely known software for statistical analysis of earthquake data, showing a better performance in evaluating b values for earthquake catalogs containing small number of events.
在描述地震频率-震级分布的古登堡-里希特关系中，b 值代表分布的斜率。由于 b 值可用于绘制震源的动力响应图，因此计算稳健 b 值的方法非常重要。虽然如今用于地震数据分析的统计软件可以高精度地确定 b 值，但在包含少量地震事件的目录中，结果并不令人满意。在本文中，我们提出了一种新的自优化算法，以更有效地计算 b 值。将算法的结果与两种广泛用于地震数据分析的统计分析软件进行比较，结果表明，在评估包含少量事件的地震目录的 b 值方面，该算法具有更好的性能。
