The constrained minimum vertex cover problem on bipartite graphs (the Min-CVCB problem) is an NP-complete problem. This paper presents a polynomial time approximation algorithm for the problem based on the technique of chain implication. For any given constant Ɛ 0, if an instance of the Min-CVCB problem has a minimum vertex cover of size (ku, kl), our algorithm constructs a vertex cover of size (ku*, kl* ), satisfying max{ku*/ku, kl* /kl} ≤ 1 + Ɛ.
