Modified:

The following optional group will configure the Big Bang – Big Crunch (BB-BC) algorithm and will be processed if [ProgramType] is set to “SamplingAlgorithm”. 

BeginSamplingAlg
MaxEvaluations  
EndSamplingAlg

BeginSamplingAlg
MaxEvaluations      100
EndSamplingAlg

Where BeginSamplingAlg and EndSamplingAlg are parsing tags that wrap the following set of algorithm configuration variables:

  • MaxEvaluations: The computational budget. The default value is 100.
