The degree of matching is commonly measured by the reflectance coefficient, as shown in (11).
The child vector was defined by the mutation operation of a real-valued coefficient by sampling a real value from a Gaussian distribution and by adding it to the coefficient as shown in (4).
The influence of the tip speed ratio is also investigated at the optimal pitch and twist angles to observe their combined effect on the power coefficient as shown in Figure15.The tip speed is varying here by the rotational speed.
It is concluded that reference circle diameter above is imprecise to calculate the cylindrical gear volume, because it is not associated with modification coefficient, addendum coefficient, tip clearance coefficient as shown in Eq. (4).
Quality of the solutions to the problem (quality of the chromosomes) is determined based on the summation of the total profit and the customer satisfaction index with a weight coefficient as shown in Eq. (1).
The cost-weighted Gini coefficient, as shown in Eq. (9), additionally considers variant-specific costs: G^{text{std}} textmathop sum limits_{v = 0}^{n} left( {w_{v}^{text{std}} } right)^{2}, (8) G_{text{cost}} textmathop sum limits_{v = 0}^{n} left( {w_{v}^{text{std}} } right)^{2} C_{v,0}.
