@Generated public final class CoolingScheduleStrategy extends com.google.protobuf.GeneratedMessage implements CoolingScheduleStrategyOrBuilder
 The cooling schedule strategy defines how to compute the current simulated
 annealing temperature t given
 - the initial temperature t0
 - the final temperature t1
 - the current search progress 0 <= p <= 1

 The value of t0 and t1 is defined by the initial_temperature and
 final_temperature in SimulatedAnnealingParameters, respectively.

 The search progress p is derived, at any given time, by the search limits.
 In particular, p measures how far we are in the search process w.r.t. to the
 number of explored solutions and the time limit.

 The temperature t, computed according to one of the strategies defined below,
 together with the selected AcceptanceStrategy, is used to guide the search
 trajectory. In particular, given a neighbor solution S', generated by the
 the application of the perturbation and improvement step to a reference
 solution S, we have that S will be replaced by S' iff
 cost(S') + t * log(U(0, 1)) < cost(S)
 where U(0, 1) is a random number sampled from a uniform distribution of real
 numbers in [0, 1].
