Completing Partial Schedules for Open Shop with Unit Processing Times and Routing,sing times is solvable in . time, that is, fixed-parameter tractable parameterized by .. Various upper bounds shown using the schedule completion theorem suggest it to be likewise beneficial for the development of approximation algorithms.

Max-Closed Semilinear Constraint Satisfaction,ically restricted first-order logic, and another characterization in terms of a finite set of relations . that allow primitive positive definitions of all other relations in the class. We also present a subclass of max-closed constraints where the CSP is in .; this class generalizes the class of max

Subclasses of Baxter Permutations Based on Pattern Avoidance,nd on growth rate, and a linear time algorithm for deciding membership in each subclass. Based on the recurrence relation describing the class, we also give a polynomial time algorithm for enumeration. We finally prove that Baxter permutations are closed under inverse based on an argument inspired f

The Word Problem for Omega-Terms over the Trotter-Weil Hierarchy, language variety . in the Trotter-Weil Hierarchy and every language variety . given by an identity of .-terms, one can decide whether .. This includes the case where . is some level of the . quantifier alternation hierarchy. As an application of our results, we show that the separation problems for
