ADAPTIVE_LINESEARCH_RULE

operations_research.pdlp.Solvers.PrimalDualHybridGradientParams.LinesearchRule.ADAPTIVE_LINESEARCH_RULE =(1)

Applies the heuristic rule presented in Section 3.1 of
https://arxiv.org/pdf/2106.04756.pdf (further generalized to QP). There
is not a proof of convergence for it. It is usually the fastest in
practice but sometimes behaves poorly.

ADAPTIVE_LINESEARCH_RULE = 1;

ADAPTIVE_LINESEARCH_RULE_VALUE

CONSTANT_STEP_SIZE_RULE

operations_research.pdlp.Solvers.PrimalDualHybridGradientParams.LinesearchRule.CONSTANT_STEP_SIZE_RULE =(3)

Uses a constant step size corresponding to an estimate of the maximum
singular value of the constraint matrix.

CONSTANT_STEP_SIZE_RULE = 3;

Definition at line 6921 of file Solvers.java.

CONSTANT_STEP_SIZE_RULE_VALUE

final int operations_research.pdlp.Solvers.PrimalDualHybridGradientParams.LinesearchRule.CONSTANT_STEP_SIZE_RULE_VALUE = 3

static

Uses a constant step size corresponding to an estimate of the maximum
singular value of the constraint matrix.

CONSTANT_STEP_SIZE_RULE = 3;

Definition at line 6958 of file Solvers.java.

LINESEARCH_RULE_UNSPECIFIED

operations_research.pdlp.Solvers.PrimalDualHybridGradientParams.LinesearchRule.LINESEARCH_RULE_UNSPECIFIED =(0)

LINESEARCH_RULE_UNSPECIFIED = 0;

MALITSKY_POCK_LINESEARCH_RULE

operations_research.pdlp.Solvers.PrimalDualHybridGradientParams.LinesearchRule.MALITSKY_POCK_LINESEARCH_RULE =(2)

Applies Malitsky & Pock linesearch rule. This guarantees an
ergodic O(1/N) convergence rate https://arxiv.org/pdf/1608.08883.pdf.
This is provably convergent but doesn't usually work as well in practice
as ADAPTIVE_LINESEARCH_RULE.

MALITSKY_POCK_LINESEARCH_RULE = 2;

Definition at line 6912 of file Solvers.java.

MALITSKY_POCK_LINESEARCH_RULE_VALUE
