Method Detail

getCoolingScheduleStrategyValue

int 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.

getCoolingScheduleStrategy

CoolingScheduleStrategy.Value getCoolingScheduleStrategy()

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

.operations_research.CoolingScheduleStrategy.Value cooling_schedule_strategy = 1;

Returns:

The coolingScheduleStrategy.

hasInitialTemperature

boolean hasInitialTemperature()

 The initial temperature. See CoolingScheduleStrategy for its usage.
 

optional double initial_temperature = 2;

Returns:

Whether the initialTemperature field is set.

getInitialTemperature

double getInitialTemperature()

 The initial temperature. See CoolingScheduleStrategy for its usage.
 

optional double initial_temperature = 2;

Returns:

The initialTemperature.

hasFinalTemperature

boolean hasFinalTemperature()

 The final temperature. See CoolingScheduleStrategy for its usage.
 

optional double final_temperature = 3;

Returns:

Whether the finalTemperature field is set.

getFinalTemperature

double getFinalTemperature()

 The final temperature. See CoolingScheduleStrategy for its usage.
 

optional double final_temperature = 3;

Returns:

The finalTemperature.

hasAutomaticTemperatures

boolean hasAutomaticTemperatures()

 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:

Whether the automaticTemperatures field is set.

getAutomaticTemperatures

boolean 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.
