 Given a large number of black-box optimizers (BBO) versions/variants which still keep increasing almost every week,
 we need some (possibly) widely acceptable criteria to select from them, as presented below in details. For any
 **new/missed** BBO in the literature, we have provided an open-access (unified API) interface to help freely add
