All values in IterationStats assume that the primal quadratic program is a minimization problem and the dual is a maximization problem. Problems should be transformed to this form if they are not already in this form. The dual vector is defined to be the vector of multipliers on the linear constraints, that is, excluding dual multipliers on variable bounds (reduced costs).

| Builder com.google.ortools.pdlp.IterationStats.Builder.setCumulativeKktMatrixPasses | ( | double | value | ) |
The cumulative number of passes through the KKT matrix since the start of the solve. One pass is a multply by the constraint matrix, its transpose and the matrix that defines the quadratic part of the objective. For example, each iteration of mirror saddle prox contributes 2.0 to this sum. This is a float because it can include fractional passes through the data. For example, in an active set method we may only use a submatrix with 20% of the nonzeros of the KKT matrix at each iteration in which case 0.2 would be added to the total.
