public class AnnealingTuneProfile extends AbstractLoadBalancingProfile
Modifier and Type  Field and Description 

protected float 
decreaseRatio
This parameter defines how fast does it will stop generating random numbers.

protected double 
maxDeviation
The percentage of deviation of the current mean to the mean
when the system was considered stable.

protected int 
maxGuessToStable
The maximum number of guesses of number generated that were already tested
for the algorithm to consider the current best solution stable.

protected long 
minSamplesToAnalyse
The minimum number of samples that must be collected before an analysis is triggered.

protected long 
minSamplesToCheckConvergence
The minimum number of samples to be collected before checking if the performance profile has changed.

protected int 
size
The initial bundle size to start from.

protected float 
sizeRatioDeviation
This parameter defines the multiplicity used to define the range available to
random generator, as the maximum.

Constructor and Description 

AnnealingTuneProfile()
Initialize this profile with default values.

AnnealingTuneProfile(TypedProperties config)
