setAlpha​

function setAlpha(uint128 numerator, uint128 denominator) external

Set the alpha parameter used in the membership score formula. Alpha is defined as a fraction in the range (0, 1) and constrained to (0,20) / (0,20], so a minimum of 1/20 and a maximum of 19/20.

Parameters​

NameTypeDescription
numeratoruint128the numerator of the fraction, must be in the range (0, 20)
denominatoruint128the denominator of the fraction, must be in the range (0, 20] and greater than the numerator
