mu: FP

The factor to squeeze complementary slackness.

alpha: FP

The factor to decrease residuals in the backtracking line search.

beta: FP

The factor to decrease a step size in the backtracking line search.

s_coef: FP

The factor to determine an initial step size in the backtracking line search.

margin: FP

Initial margin value for dual variables of inequalities.
