Detailed Description

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).

◆ getCumulativeKktMatrixPasses()

double operations_research.pdlp.SolveLogOuterClass.IterationStats.getCumulativeKktMatrixPasses ( )

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.

optional double cumulative_kkt_matrix_passes = 4;

Returns: The cumulativeKktMatrixPasses.

◆ getCumulativeRejectedSteps()

int operations_research.pdlp.SolveLogOuterClass.IterationStats.getCumulativeRejectedSteps ( )

The total number of rejected steps (e.g., within a line search procedure)
since the start of the solve.

optional int32 cumulative_rejected_steps = 5;

Returns: The cumulativeRejectedSteps.

Implements operations_research.pdlp.SolveLogOuterClass.IterationStatsOrBuilder.

Definition at line 10840 of file SolveLogOuterClass.java.

◆ getCumulativeTimeSec()

double operations_research.pdlp.SolveLogOuterClass.IterationStats.getCumulativeTimeSec ( )

The amount of time passed since we started solving the problem (see solver
log `solve_time_sec` which records total time).

optional double cumulative_time_sec = 6;

Returns: The cumulativeTimeSec.

◆ getInfeasibilityInformation()

operations_research.pdlp.SolveLogOuterClass.InfeasibilityInformation operations_research.pdlp.SolveLogOuterClass.IterationStats.getInfeasibilityInformation ( int index )

A set of statistics measuring how close a point is to establishing primal
or dual infeasibility (i.e., has no solution). This field is repeated since
there might be several different points that could establish infeasibility.
