宇宙学常数的成功人择预测关键取决于先验分布平坦的假设。然而，以前的计算简化景观模型表明，先验分布是交错的，这表明与人为预测的冲突。在这里，我们分析计算完整的分布，包括先验和人择选择的影响，一个玩具景观模型与现实的真空数，N = 10500。我们表明，它是可能的分形先验分布，我们发现表现为一个有效的平坦分布在广泛的一类景观，取决于制度的参数空间。这种可能性是否实现取决于目前未知的景观细节。
The successful anthropic prediction of the cosmological constant depends crucially on the assumption of a flat prior distribution. However, previous calculations for simplified landscape models showed that the prior distribution is staggered, suggesting a conflict with anthropic predictions. Here we analytically calculate the full distribution, including the prior and anthropic selection effects, for a toy landscape model with a realistic number of vacua, N∼10500. We show that it is possible for the fractal prior distribution that we find to behave as an effectively flat distribution in a wide class of landscapes, depending on the regime of parameter space. Whether or not this possibility is realized depends on currently unknown details of the landscape.
