In this work, we use the algebra of coupled scalars to construct integrable couplings of the generalized Vakhnenko equation. We use the Cole–Hopf transformation and the simplified Hirota’s method to study the developed couplings. We show that these couplings exhibit soliton solutions and anti-soliton solutions consecutively.
