Deep inference names a general idea in structural proof theory that breaks with the classical sequent calculus by generalising the notion of abstract structure structure to permit inference to occur in contexts of high structural complexity. The term deep inference is generally reserved for proof calculi where the structural complexity is unbounded in this article we will use non shallow inference to refer to calculi that have structural complexity greater than the sequent calculus, but not unboundedly so, although this is not at present established terminology. Deep inference is not important in logic outside of structural proof theory, since the phenomena that lead to the proposal of formal system s with deep inference are all related to the cut elimination theorem . The first calculus of deep inference was proposed by Kurt Sch tte , but the idea did not generate much interest at the time. Nuel Belnap proposed display logic in an attempt to characterise the essence of structural proof theory. The calculus of structures was proposed in order to give a cut free characterisation of noncommutative logic .

In informal logic , an inference objection argument objection is an objection to an argument based not on any of its stated premises, but rather on the relationship between premise and Main contention contention . For a given simple argument, if the assumption is made that its premises are correct, fault may be found in the progression from these to the conclusion of the argument. This can often take the form of an unstated co premise , as in Begging the question . In other words, it may be necessary to make an assumption in order to conclude anything from a set of true statements. This assumption must also be true in order that the conclusion follow logically from the initial statements. Example Image NASA Stardust Mission inference objection.png thumb left 175px An example of an inference objection based on NASA s Stardust Mission . ref http www.newscientist.com article mg18124314.400 doom in the sky.html Doom in the sky? 24 January 2004 New Scientist Bot generated title ref Image Stardust Mission Inference objection with co premise included.png thumb right 200px The same argument with the originally unstated co premise included.

The objection is therefore placed beside the main premise and exactly corresponds to an unstated or hidden co premise. This is demonstrated by the argument map to the right in which the full pattern of reasoning relating to the contention is set out.

In constraint satisfaction , constraint inference is a relationship between constraints and their consequences. A set of constraints math D math entails a constraint math C math if every solution to math D math is also a solution to math C math . In other words, if math V math is a valuation of the variables in the scopes of the constraints in math D math and all constraints in math D math are satisfied by math V math , then math V math also satisfies the constraint math C math . Some operations on constraints produce a new constraint that is a consequence of them. Constraint composition operates on a pair of binary constraints math x,y ,R math and math y,z ,S math with a common variable. The composition of such two constraints is the constraint math x,z ,Q math that is satisfied by every evaluation of the two non shared variables for which there exists a value of the shared variable math y math such that the evaluation of these three variables satisfies the two original constraints math x,y ,R math and math y,z ,S math . Constraint projection restricts the effects of a constraint to some of its variables. Given a constraint math t,R math its projection to a subset math t math of its variables is the constraint math t ,R math that is satisfied by an evaluation if this evaluation can be extended to the other variables in such a way the original constraint math t,R math is satisfied. Extended composition is similar in principle to composition, but allows for an arbitrary number of possibly non binary constraints the generated constraint is on an arbitrary subset of the variables of the original constraints. Given constraints math C 1, ldots,C m math and a list math A math of their variables, the extended composition of them is the constraint math A,R math where an evaluation of math A math satisfies this constraint if it can be extended to the other variables so that math ...
