Detailed Description

class BipartiteGraphBicoloring in group22.

Bipartite graph bicoloring is an assignment of colors to subsets of column and row vertices of the bipartite graph of a Jacobian matrix. The present version of ColPack provides methods for star bicoloring only. The distance-one coloring constraint is satisfied by all bicoloring algorithms by selecting colors for row and column vertices from two disjoint sets of colors. Sizes of the sets are equal to the number of row and column vertices respectively, which are the maximum number of colors that can be required by the row or column vertices.

In star bicoloring, vertex cover can be computed either explicitly or implicitly. An explicit vertex cover is computed and used to determine which vertices are to be colored. An implicit vertex cover is computed by including vertices as they get colored, into the cover and is used to determine the end of coloring as a vertex cover is reached. In both cases pre-computed vertex ordering determines the order in which vertices are colored. In implicit vertex cover, a vertex is not selected as a candidate vertex to be colored if no edge is incident on the vertex which has not been covered by any other colored vertex.

Generate and return the Left Seed matrix. This Seed matrix is managed and freed by ColPack.

Precondition:

the Graph has been Bicolored

Postcondition:

Size of the returned matrix is (*ip1_SeedRowCount) rows x (*ip1_SeedColumnCount) columns. (*ip1_SeedColumnCount) == num of rows of the original matrix == GetRowVertexCount() (*ip1_SeedRowCount) == num of colors used to color the left (row) vertices excluding color 0.

Notes:

Vertices with color 0 are ignored. That also means left (row) vertices with color 1 will be grouped together into the first row (row 0) of the seed matrix and so on.
