getAutomaticTemperatures()

boolean com.google.ortools.constraintsolver.SimulatedAnnealingParametersOrBuilder.getAutomaticTemperatures

(

)

Automatically define the value for the temperatures as follows.
First, a  reference temperature t is defined as
w1 * c1 + w2 * c2 + ... + wK * cK
where 0 < wJ <= 1 is the fraction of vehicles of cost class J and cJ is the
average arc cost for the cost class J.
The value of cJ is identified by randomly sampling N arc costs for the cost
class J, where N is equal to the number of instance nodes.
The initial and final temperatures are then defined as
- initial_temperature: 0.1 * t
- final_temperature: 0.001 * t

optional bool automatic_temperatures = 4;

Returns

The automaticTemperatures.

Implemented in com.google.ortools.constraintsolver.SimulatedAnnealingParameters.Builder, and com.google.ortools.constraintsolver.SimulatedAnnealingParameters.

getCoolingScheduleStrategy()

com.google.ortools.constraintsolver.CoolingScheduleStrategy.Value com.google.ortools.constraintsolver.SimulatedAnnealingParametersOrBuilder.getCoolingScheduleStrategy

(

)

Determines the speed at which the temperature changes from initial to
final.

.operations_research.CoolingScheduleStrategy.Value cooling_schedule_strategy = 1;

Returns

The coolingScheduleStrategy.

Implemented in com.google.ortools.constraintsolver.SimulatedAnnealingParameters.Builder, and com.google.ortools.constraintsolver.SimulatedAnnealingParameters.

getCoolingScheduleStrategyValue()

int com.google.ortools.constraintsolver.SimulatedAnnealingParametersOrBuilder.getCoolingScheduleStrategyValue

(

)

Determines the speed at which the temperature changes from initial to
final.

.operations_research.CoolingScheduleStrategy.Value cooling_schedule_strategy = 1;

Returns

The enum numeric value on the wire for coolingScheduleStrategy.

Implemented in com.google.ortools.constraintsolver.SimulatedAnnealingParameters.Builder, and com.google.ortools.constraintsolver.SimulatedAnnealingParameters.

getFinalTemperature()

double com.google.ortools.constraintsolver.SimulatedAnnealingParametersOrBuilder.getFinalTemperature

(

)

The initial and final temperatures are then defined as
- initial_temperature: 0.1 * t
- final_temperature: 0.001 * t

optional bool automatic_temperatures = 4;

Returns

Whether the automaticTemperatures field is set.

Implemented in com.google.ortools.constraintsolver.SimulatedAnnealingParameters.Builder, and com.google.ortools.constraintsolver.SimulatedAnnealingParameters.
