By checking the ZipfianGenerator code in the repository, the default value for alpha is
1/(1-theta)(line 142).Theta is the 'zipfian constant' (line 137). Its default value is
0.99(line 42), which gives an alpha value of100.You can specify a different theta in the constructor to get a different alpha value.
