This paper deals with the control problem of right linear grammars with unknown behaviors (RLUBs, for short) in which derivation behavior is not determined completely. In particular, we discuss on the size of control alphabets of control systems which regulate RLUBs in order to generate a target string only. We contribute to the reduction of control alphabet size from $O(l)$ to $O(\log l)$, where l is a parameter related to reaction conditions under which RLUBs are chemically implemented.

减少控制字母的大小，以控制行为未知的右线性语法

本文研究了具有未知行为的右线性语法（简称RLUB）的控制问题，在该问题中，派生行为尚未完全确定。特别地，我们讨论控制系统的控制字母的大小，该控制系统调节RLUB以仅生成目标字符串。我们为减少控制字母的大小做出了贡献$Ø（升）$ 到 $Ø（\mathrm{日志}升）$，其中l是与化学合成RLUB的反应条件有关的参数。
