In addition, programmers have come up with all sorts of algorithms and tricks such as Alpha-Beta pruning, Negascout, and MTD(f) in order to lessen the number of nodes the computer must examine.

此外，程序员们也提出了很多算法和技巧来减少节点数目，比如阿尔法 贝塔剪枝算法（Alpha-Beta pruning），Negascout搜索算法以及MTD（全称是：Memory enhanced Test Driver，即记忆增强测试驱动，译者注）方法。

But the trouble with such areas may not be the absence of alpha but the level of "beta", or market return.

但这些领域的问题不是缺“阿尔法”，而是缺贝塔或者说市场回报。

The most damaging radiation are gamma rays and x-rays; energetic alpha rays (streams of helium nuclei) and beta rays (electrons) can also damage cells.

最具破坏力的辐射是伽马射线和X射线；能量强大的阿尔法射线（氦核能量流）和贝塔射线（电子流）也可以破坏细胞组织。

Let's just check. If my pair chooses Alpha, then my choosing Alpha yields 0, Beta -3: so Alpha would be better.

我们来验证下,如果我对手选α,我选α得0,选β得-3,所以选α更好

But if my pair chooses Beta then Alpha yields -1, Beta yields 1: in this case Beta would be better.

但是要是我对手选β我选α得-1,选β得1,此时选β更好

If my opponent chooses Alpha and I choose Alpha, I get 0; Beta, I get -1. So Alpha would be better.

如果我对手选α我选α,我得0,选β我得-1,选α更好

Vega is not actually part of the true Greek alphabet (Alpha-Beta) that is so beloved by financial quants etc and yet it fits neatly into the family tree of performance benchmarks.

The gene converts the compound phytoene into lycopene, which in turn is involved in the production of alpha and beta-carotene.

The following Exhibit compares R-Squared, Beta, and Alpha for two hypothetical large-cap equity funds, and will be used to demonstrate how investors can more meaningfully compare the performance of mutual funds.
