 The initial temperature. See CoolingScheduleStrategy for its usage.

 Gets whether the "final_temperature" field is set.
bool AutomaticTemperatures [get, set]
 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.
bool HasAutomaticTemperatures [get]
 Gets whether the "automatic_temperatures" field is set.
