Patch Graph Rewritinglanguage with precise formal semantics. The language has rich expressive power in two ways. First, rewrite rules can flexibly constrain the permitted shapes of patches touching matching subgraphs. Second, rules can freely transform patches. We highlight the framework’s distinguishing features by comparing it against existing approaches.作者: 溝通 時(shí)間: 2025-3-22 02:05
