Alpha–beta pruning is a search algorithm that seeks to decrease the number of nodes that are evaluated by the minimax algorithm in its search tree. It is an adversarial search algorithm used commonly for machine playing of two-player combinatorial games ( Tic-tac-toe , Chess , Connect 4 , etc.).
If p(t) exceeds an arbitrary cutoff value (originally 7.5e–3), the mean of the p(j)'s exceeds 1, and p(t) exceeds the alpha helix and beta sheet probabilities for that window, then a turn is predicted. If the first two conditions are met but the probability of a beta sheet p(b) exceeds p(t), then a sheet is predicted instead.
The alpha roll is a dog training technique that is considered outdated by many modern-day dog trainers. The theory behind the training method is that dogs are hierarchical animals. The technique is used to teach the dog that the trainer or owner of the dog is the pack leader (alpha animal). Methods include when a dog misbehaves to pin the dog ...

In the case of other wild canids, the alpha male may not have exclusive access to the alpha female; [23]: 502 [obsolete source] moreover, other pack members may guard the maternity den used by the alpha female; as with the African wild dog, Lycaon pictus. [24] [full citation needed]
The procedure proposed by Dunn [2] can be used to adjust confidence intervals. If one establishes m {\displaystyle m} confidence intervals, and wishes to have an overall confidence level of 1 − α {\displaystyle 1-\alpha } , each individual confidence interval can be adjusted to the level of 1 − α m {\displaystyle 1-{\frac {\alpha }{m}}} .
In probability and statistics, the truncated normal distribution is the probability distribution derived from that of a normally distributed random variable by bounding the random variable from either below or above (or both).
Alpha cutoff frequency, or is the frequency at which the common base DC current gain drops to 0.707 of its low frequency value. The common base DC current gain is the ratio of a transistor's collector current to the transistor's emitter current , or α = i C i E {\displaystyle \alpha ={\frac {i_{C}}{i_{E}}}} .
