High-performance solver for binary quadratic problems
Timotej Hrga, Janez Povh, Angelika Wiegele
Objavljeni povzetek znanstvenega prispevka na konferenci
Oznake: visoko zmogljivo računalništvo;kombinatorična optimizacija;problem maksimalnega prereza;high-performance computing;combinatorial optimization;max-cut problem;
Many problems in combinatorial optimization can be formulated as constrained binary quadratic problems(BQPs),which are in genera lNP hard. We present a method for finding exact solutions of large-scale linearly constrained binary quadratic programming problems. Our exact solution method combines para ...

Application of semidefinite programming and high-performance computing in discrete optimization
Timotej Hrga, Janez Povh, Angelika Wiegele
Doktorska disertacija
Oznake: mathematics;combinatorial optimization;Max-Cut problem;semidefinite programming;alternating direction method of multipliers;branch-and-bound;high-performance computing;
Pri problemu maksimalnega prereza grafa iščemo tako delitev množice vozlišč na dva dela, da je vsota uteži na povezavah, ki imajo krajišča v različnih delih particije, največja. V disertaciji študiramo semidefinitne poenostavitve tega kombinatoričnega problema in uporabo dobljenih mej zn ...

Novel alignment method for optical 3D gear metrology of spur gears with a plain borehole
Uroš Urbas, Timotej Hrga, Janez Povh, Nikola Vukašinović
Izvirni znanstveni članek
Oznake: gears;optical inspection;geometrical quality parameters;alignment;SGA;
In 3D optical metrology, novel approaches to characterise the geometrical quality of gears require a custom gear alignment process to produce reliable results. This study proposes a novel scan alignment method known as subsequent gear alignment (SGA). It emphasises on the proper alignment of the gea ...

Four algorithms to solve symmetric multi-type non-negative matrix tri-factorization problem
Rok Hribar, Timotej Hrga, Gregor Papa, Gašper Petelin, Janez Povh, Nataša Pržulj, Vida Vukašinović
Izvirni znanstveni članek
Oznake: non-negative matrix factorization;fixed point method;block coordinate descent;projected gradient method;adaptive moment estimation method;
In this paper, we consider the symmetric multi-type non-negative matrix tri-factorization problem (SNMTF), which attempts to factorize several symmetric non-negative matrices simultaneously. This can be considered as a generalization of the classical non-negative matrix tri-factorization problem and ...
