SCIP_Row Struct Reference
Detailed Description
LP row The column vector of the LP row is partitioned into two parts: The first row->nlpcols columns in the cols array are the ones that belong to the current LP (row->cols[j]->lppos >= 0) and that are linked to the row (row->linkpos[j] >= 0). The remaining row->len - row->nlpcols columns in the cols array are the ones that don't belong to the current LP (row->cols[j]->lppos == -1) or that are not linked to the row (row->linkpos[j] == -1).
