Inverting Onto Functions and Polynomial Hierarchy
The class TFNP, defined by Megiddo and Papadimitriou, consists of multivalued functions with values that are polynomially verifiable and guaranteed to exist. Do we have evidence that such functions are hard, for example, if TFNP is computable in polynomial-time does this imply the polynomial-time hierarchy collapses? By computing a multivalued function in deterministic polynomial-time we mean o...
متن کاملThe Hierarchy of Evidence
The Hierarchy of evidence is based on summaries from the National Health and Medical Research Council (2009), the Oxford Centre for Evidence-based Medicine Levels of Evidence (2011) and Melynyk and Fineout-Overholt (2011). Ι Evidence obtained from a systematic review of all relevant randomised control trials. ΙΙ Evidence obtained from at least one well designed randomised control trial. ΙΙΙ Evi...
متن کاملEvidence and the hierarchy of mathematical theories
It is a well-known fact of mathematical logic, by now developed in considerable detail, that formalized mathematical theories can be ordered by relative interpretability, and the "strength" of a theory is indicated by where it stands in this ordering. Mutual interpretability is an equivalence relation, and what I call an ordering is a partial ordering modulo this equivalence. Of the theories th...
متن کاملInverting the Furstenberg correspondence
Given a sequence of sets An ⊆ {0, . . . , n − 1}, the Furstenberg correspondence principle provides a shift-invariant measure on 2 that encodes combinatorial information about infinitely many of the An’s. Here it is shown that this process can be inverted, so that for any such measure, ergodic or not, there are finite sets whose combinatorial properties approximate it arbitarily well. The finit...
متن کاملInverting the organisational pyramid
In any healthcare institution, the most important people are patients and their families [1]. These people benefit from the services of the institution, pay for these services either directly or indirectly through third-party payers, and hence affect the marketing of the institution through expressions of satisfaction (or dissatisfaction) with the services. They also form a customer base for re...
