◆ clearAutomaticTemperatures()

Builder com.google.ortools.constraintsolver.SimulatedAnnealingAcceptanceStrategy.Builder.clearAutomaticTemperatures ( )

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: This builder for chaining.
