“…where ϕ ∈ (0, 1/2), ρ ∈ (ϕ, 1) and ϕ 1 ∈ (0, ϕ). Further study can be found in [45]. Based on the innovation of the YWL line search technique, Yuan et al [41] focused on the usual Armijo line search technique and proposed a modified Armijo line search technique as follows: 9) where λ, γ ∈ (0, 1), λ 1 ∈ (0, λ), and α k is the largest number of {γ k | k = 0, 1, 2, .…”
