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.
[28] [29] [30] Fisher suggested a probability of one in twenty (0.05) as a convenient cutoff level to reject the null hypothesis. [31] In a 1933 paper, Jerzy Neyman and Egon Pearson called this cutoff the significance level , which they named α {\displaystyle \alpha } .

In probability theory and statistics, the beta distribution is a family of continuous probability distributions defined on the interval [0, 1] or (0, 1) in terms of two positive parameters, denoted by alpha (α) and beta (β), that appear as exponents of the variable and its complement to 1, respectively, and control the shape of the distribution.
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}}} .
The SPRT is currently the predominant method of classifying examinees in a variable-length computerized classification test (CCT) [citation needed].The two parameters are p 1 and p 2 are specified by determining a cutscore (threshold) for examinees on the proportion correct metric, and selecting a point above and below that cutscore.
