Constraint Satisfaction with Countable Homogeneous Templates,roper generalization of constraint satisfaction with finite templates. If the age of Γ is finitely axiomatizable, then CSP(Γ) is in NP. If Γ is a digraph we can use the classification of homogeneous digraphs by Cherlin to determine the complexity of CSP(Γ).

Quantified Constraints: Algorithms and Complexity,tential quantifiers. We show that the complexity of such extended problems is determined by the surjective polymorphisms of the constraint predicates. We give examples to illustrate how this result can be used to identify tractable and intractable cases for the quantified constraint satisfaction problem over arbitrary finite domains.

Positive Games and Persistent Strategies, are unexpectedly simple. On the contrary, infinite game graphs, as well as infinite alphabets, yield positive sets involved in non determined games..Last, we discuss positive Muller winning conditions. Although they do not help to discriminate between memoryless and LAR winning strategies, they bear a strong topological characterization.

The Biology of Early Influences power of the logic. Our logic can express the graph isomorphism problem and we show that, on almost all structures, it captures . ., the class of problems decidable in polynomial time by a deterministic Turing machine with an oracle for graph isomorphism.

The Commuting V-Diagram,diagram inspired by the V-process model is able to clarify the issues involved. This V-diagram defines the dependencies of specifications, implementations and test-cases in the category of contracts. The objects in this category are contracts defined in the formalism of the refinement calculus. The
