The Tractability Frontier of Well-designed SPARQL Queries

Summary: Characterizes tractable evaluation for well-designed SPARQL queries using only AND, OPTIONAL, and UNION. Introduces domination width—a treewidth-based structural measure—and shows bounded domination width exactly captures polynomial-time evaluability under standard complexity assumptions.
