A Knee Point-Driven Many-Objective Evolutionary Algorithm with Adaptive Switching Mechanism

Algorithm 8

Association (, ).

Input: P (population), F_l (critical front)

1 For each x_j ∈ F_l

2   θ (x_j) = ∞

3   γ (x_j) = -1

4   For each c_k∈ P

5     Calculate angle μ between x_j and c_k by Eq. (15)

6     Ifμ < θ (x_j)

7        θ (x_j) = μ

8        γ (x_j) = k

9     End If

10   End For

11 End For
