The integration of an approximate model and a clonal selection algorithm (CSA) is considered as one of the most effective ways to solve complex optimization design problems in engineering. In this study, first, a process for developing an approximate model and the principles of clonal selection algorithms is presented. Second, a variotherm temperature injection mold was used to produce a large ...

We extend the restrictions which induce unique parsability in Chomsky grammars to accepting grammar systems. It is shown that the accepting power of global RC-uniquely parsable accepting grammar systems equals the computational power of deterministic pushdown automata. More computational power, keeping the parsability without backtracking, is observed for local accepting grammar systems satisfy...

You do not know who this Zhuangzi is, not even if it is the name of a man; you don’t know either what a shi or a cheng is. But on the basis of the author's authority, you believe that the sentence “Zhuangzi's principle is that you cannot get a shi without having a cheng” is true. You do not understand this sentence, for you do not know what it means, therefore you don't believe that Zhuangzi's ...

We consider several types of pure grammars and systems as language acceptors and compare them to their generating counterparts. In contrast with the case (considered in earlier papers of the authors) encountered when admitting nonterminals in these classical string rewriting mechanisms , we get incomparability results between language families generated and accepted by numerous types of pure gr...
