◆ 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.

◆ 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.

◆ 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;
