public class BBOBenchmarks
extends Problem
implements SimpleProblemForm

The Black Box Optimization workshop (BBOB) has an annual competition for doing real-valued parameter optimization. The examples shown here are more or less faithful reproductions of the BBOB 2010 C code, only using Mersenne Twister instead of BBOB's random number generator. Unfortunately, the original BBOB code has various magic numbers, unexplained variables, and unfortunate algorithmic decisions. We've reproduced them exactly rather than attempt to convert to a standard ECJ template, and simply apologize beforehand.

Parameters

base.`noise` String = `none` (default) `, gauss, uniform, cauchy, gauss-moderate, uniform-moderate, cauchy-moderate`	(what type of noise (if any) to add to the function value)
base.`reevaluate-noisy-problems` boolean = `true`(default)	(whether to reevaluate noisy problems)

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`void`	`evaluate(EvolutionState state, Individual ind, int subpopulation, int threadnum)` Evaluates the individual in ind, if necessary (perhaps not evaluating them if their evaluated flags are true), and sets their fitness appropriately.
`void`	`setup(EvolutionState state, Parameter base)` Sets up the object by reading it from the parameters stored in state, built off of the parameter base base.

public void setup(EvolutionState state,

```
    Description copied from interface: Prototype
    
    Sets up the object by reading it from the parameters stored in state, built off of the parameter base base. If an ancestor implements this method, be sure to call super.setup(state,base); before you do anything else.
    For prototypes, setup(...) is typically called once for the prototype instance; cloned instances do not receive the setup(...) call. setup(...) may be called more than once; the only guarantee is that it will get called at least once on an instance or some "parent" object from which it was ultimately cloned.
    
    Specified by:
    
    setup in interface Prototype

                     int threadnum)
```
    Description copied from interface: SimpleProblemForm
    
    Evaluates the individual in ind, if necessary (perhaps not evaluating them if their evaluated flags are true), and sets their fitness appropriately.
