For a matching M in a graph G, let G (M) be the subgraph of G induced by the vertices of G that are incident with an edge in M. The matching M is induced, if G (M) is 1-regular, and M is uniquely restricted, if M is the unique perfect matching of G (M). The induced matching number ν s (G) of G is the largest size of an induced matching in G, and the uniquely restricted matching number ν u r (G) of G is the largest size of a uniquely restricted matching in G. Golumbic et al.(2001)[4] posed the problem to characterize the graphs G with ν s (G)= ν u r (G). We give a complete characterization of the 2-connected subcubic graphs G of sufficiently large order with ν s (G)= ν u r (G). As a consequence, we are able to show that the subcubic graphs G with ν s (G)= ν u r (G) can be recognized in polynomial time.
