Small models of convex fragments of definable subsets

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
This article discusses the problems of that part of Model Theory that studies the properties of countable models of inductive theories with additional properties, or, in other words, Jonsson theories.

Another bijection between $2$-triangulations and pairs of non-crossing Dyck paths [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
A $k$-triangulation of the $n$-gon is a maximal set of diagonals of the $n$-gon containing no subset of $k+1$ mutually crossing diagonals. The number of $k$-triangulations of the $n$-gon, determined by Jakob Jonsson, is equal to a $k \times k$ Hankel ...

Why are CSPs Based on Partition Schemes Computationally Hard? [PDF]

open access: yes, 2018
Many computational problems arising in, for instance, artificial intelligence can be realized as infinite-domain constraint satisfaction problems (CSPs) based on partition schemes: a set of pairwise disjoint binary relations (containing the equality ...

Hom complexes of set systems [PDF]

open access: yes, 2013
A set system is a pair S = (V (S), Delta(S)), where Delta(S) is a family of subsets of the set V(S). We refer to the members of Delta(S) as the stable sets of S.

A fragment of a theoretical set and its strongly minimal central type [PDF]

open access: yes, 2023
The paper defines a new class of algebras, the theory of which is a special case of Jonsson theories. This class applies to both varieties and Jonsson theories. The main results of this article are the following two results. In this article, an answer is

Set Function Optimization [PDF]

open access: yes, 2018
This article is an introduction to recent development of optimization theory on set functions, the nonsubmodular optimization, which contains two interesting results, DS (difference of submodular) functions decomposition and sandwich theorem, together ...

Companions of the fragments in the Jonsson enrichment

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2017
In this article we consider the properties of central types for the existentially prime strongly convex Jonsson theories in some extension. This class of theories is a subclass of a broad class of Jonsson theories.

Double factorization of the Jonsson spectrum

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
First of all, we have to note that in this article, we introduced the new concepts of relations between Jonsson theories in the class of cosemanticness for some considered Jonsson spectrum.

Computing the minimum EDF feasible deadline in periodic systems [PDF]

open access: yes, 2006
In most real-time applications, deadlines are artifices that need to be enforced to meet different performance requirements. For example, in periodic task sets, jitter requirements can be met by assigning suitable relative deadlines and guaranteeing the ...

Generalized planning as heuristic search [PDF]

open access: yes, 2021
Comunicació presentada a ICAPS2021, celebrat del 2 a 13 d'agost de 2021 de manera virtual.Although heuristic search is one of the most successful approaches to classical planning, this planning paradigm does not apply straightforwardly to ...
