 The behavior of previous versions can be recovered by the ''--ga-impl ga'' command line option. The behavior of previous versions can be recovered by the ''--ga-impl ga'' command line option.
 However, ''--ga-impl ga'' requires pre-allocation of GA memory in many calculations if the ''socket'' GA runtime is used, and failing to preallocate sufficient amount of GA memory may lead to crashes or incorrect results. However, ''--ga-impl ga'' requires pre-allocation of GA memory in many calculations if the ''socket'' GA runtime is used, and failing to preallocate sufficient amount of GA memory may lead to crashes or incorrect results.
