Parser Table Compression Schemes Used In Optimizing Sparse Matrices

HIRSCHBERG'S DOMAIN

Matrix Compression Techniques     These are sparse parser table compression techniques. I've modified it to be used in matrices. These are the pseudocodes ! not the programs! Graph coloring scheme for i=0 to m-1         for j =0 to n-1                 if T[i][j] == insignificant                         sigmap[i][j] = 0                 else                         sigmap[i][j] = 1 color = 1 for i=0 to m-1         for i2=0 to m-1                 for j=0 to n-1                         if T[i][j] == T[i2][j] && T[i][j] != insignificant && T[i2][j] != insignificant                                 f = 1                         else                                 f = 0                                 rowmap[i2] = color                 if f == 1                         if rowmap[i] == color                                 rowmap[i2] = color-1                                 for j=0 to n-1                                         newT[rowmap[i2]][j] = T[i][j]                         else                                 rowmap[i2] = color                                 for j=0 to  n-1                                         newT[rowmap[i2]][j] = T[i][j]                 else                 if f == 0                         color++                         rowmap[i2] = color                         for j=0 to n-1                                 newT[rowmap[i2]][j] = T[i][j] for j=0 to n-1         for j2=0 to n-1                 for i=0 to m-1                         if T[i][j] == T[i][j2] && T[i][j] != insignificant && T[i][j2] != insignificant                                 f = 1                         else                                 f = 0                                 columnmap[j2] = color                 if f == 1                         if columnmap[j] == color                                 columnmap[j2] = color-1                                 for i=0 to m-1                                         value[columnmap[i]][j2] = T[i][j]                         else                                 columnmap[j2] = color                    hirschberg/
