,On the complementation of Büchi asynchronous cellular automata,ynchronous cellular automata for finite traces, which has been open for several years. We use the subset automaton construction in order to extend Klarlund‘s progress measure technique of complementation to non-deterministic asynchronous cellular Büchi automata for infinite traces. Our automaton for

Distribution and locality of concurrent systems, based on a set of distributed transition rules that record spatial information and on a notion of equivalence that discriminates according to which actions processes can perform and where these actions are performed. The new semantics is proven to coincide with the . of Boudol, Castellani, Hennessy

On the approximation of shortest common supersequences and longest common subsequences,hey have important applications in many areas including computational molecular biology (., sequence alignment), data compression, planning, text editing (. function in UNIX), etc. [1, 6, 7, 8, 10, 17, 19, 22, 23, 24, 26, 27]. The question of approximating SCS and LCS was raised 15 years ago in [19]

On the approximation of shortest common supersequences and longest common subsequences,t, if LCS has a polynomial-time approximation algorithm with performance ratio .., then . = .. Item (iii) is straightforward using recent breakthrough results in [3]. However, items (i) and (ii) require new ideas and techniques..In the second part of the paper, we introduce a new powerful method for
