Member Data Documentation

DANTZIG

com.google.ortools.glop.GlopParameters.PricingRule.DANTZIG =(0)

Strategy using only the reduced cost of a variable.

Note that compared to a textbook rule, we normalize the reduced cost of a
variable using the norm of the associated column. This improves quite a
bit the rule at almost no extra complexity. See the first paper from
Ping-Qi Pan cited in primal_edge_norms.h.

DANTZIG = 0;

Definition at line 343 of file GlopParameters.java.

DANTZIG_VALUE

final int com.google.ortools.glop.GlopParameters.PricingRule.DANTZIG_VALUE = 0

static

Strategy using only the reduced cost of a variable.

variable using the norm of the associated column. This improves quite a

DANTZIG = 0;

Definition at line 377 of file GlopParameters.java.

DEVEX

com.google.ortools.glop.GlopParameters.PricingRule.DEVEX =(2)

Normalize the reduced costs by an approximation of the norm of the edges.
This should offer a good tradeoff between steepest edge and speed.

DEVEX = 2;

Definition at line 362 of file GlopParameters.java.

DEVEX_VALUE

final int com.google.ortools.glop.GlopParameters.PricingRule.DEVEX_VALUE = 2

static

Normalize the reduced costs by an approximation of the norm of the edges.
This should offer a good tradeoff between steepest edge and speed.

DEVEX = 2;

Definition at line 396 of file GlopParameters.java.

STEEPEST_EDGE

com.google.ortools.glop.GlopParameters.PricingRule.STEEPEST_EDGE =(1)

Normalize the reduced costs by the norm of the edges. Since computing
norms at each step is too expensive, reduced costs and norms are
updated iteratively from one iteration to the next.

STEEPEST_EDGE = 1;

Definition at line 353 of file GlopParameters.java.

STEEPEST_EDGE_VALUE

final int com.google.ortools.glop.GlopParameters.PricingRule.STEEPEST_EDGE_VALUE = 1

static

Normalize the reduced costs by the norm of the edges. Since computing
norms at each step is too expensive, reduced costs and norms are
updated iteratively from one iteration to the next.

STEEPEST_EDGE = 1;
