The double-incompleteness theorem
(Latvia State University, 1975)Let T be a theory, Q - a metatheory of T. Under certain conditions there exist T-undecidable sentences for which this undecidability cannot be proved in Q. For English translation and proof, see K. Podnieks What is ... -
The double-incompleteness theorem
(Stiinca, Kishinev, 1976)Let T be a strong enough theory, and M - its metatheory, both are consistent. Then there is a closed arithmetical formula H that is undecidable in T, but one cannot prove in M neither that H is T-unprovable, nor that H is ... -
Probabilistic program synthesis
(Latvia State University, 1977)The following model of inductive inference is considered. Arbitrary numbering tau = {tau_0, tau_1, tau_2, ... } of total functions N->N is fixed. A "black box" outputs the values f(0), f(1), ..., f(m), ... of some function ... -
Computational complexity of prediction strategies
(Latvia State University, 1977)The value f(m+1) is predicted from given f(1), ..., f(m). For every enumeration T(n, x) there is a strategy that predicts the n-th function of T making no more than log2(n) errors (Barzdins-Freivalds). It is proved in the ... -
An Exhaustive Search Algorithm for Finding Hamiltonian Cycles
(EIK,Elektronische Informationsverarbeitung und Kybernetik, Universität Trier, Akademie Verlag, 1980)The paper suggests an exhaustive search algorithm for finding Hamiltonian circuits in an undirected graph based on depth-first search and working successfully on sparse graphs. The method is based on the idea not to ... -
Prediction of the next value of a function
(1981)The following model of inductive inference is considered. Arbitrary set tau = {tau_1, tau_2, ..., tau_n} of n total functions N->N is fixed. A "black box" outputs the values f(0), f(1), ..., f(m), ... of some function f ...
