We deΓΏne a realizability interpretation of Aczel's Constructive Set Theory CZF into Explicit Mathematics. The ΓΏnal results are that CZF extended by Mahlo principles is realizable in corresponding extensions of T0, thus providing relative lower bounds for the proof-theoretic strength of the latter.
In this paper we study the problem of estimating a given function of a vector of unknowns, called the problem element, by using measurements depending nonlinearly on the problem element and affected by unknown but bounded noise. Assuming that both the solution sought and the measurements depend poly
