Linear-time algorithm for the edge-colorability of a graph with prescribed vertex types

We consider the coloring of edges in a graph in which there are vertices of three types. In a feasible edge coloring, each vertex of the first type is incident with at least two edges of the same color, and each vertex of the second type with at least two edges of different colors; while no constrai...
