Towards smaller single-point failure-resilient analog circuits by use of a genetic algorithm
Žiga Rojec
Izvirni znanstveni članek
Oznake: analog circuits;analog circuit synthesis;circuit optimization;failure-resilience;circuit robustness;
Failure-resilient analog circuits are difficult to design, but artificial intelligence can help crawl the topology solution space. Us-ing evolutionary computation-based topology synthesis we evolve analog arcus tangent computational circuits, resilient to any rectifying diode or resistor high-impeda ...

AVTOMATSKA SINTEZA TOPOLOGIJ ANALOGNIH ELEKTRIČNIH VEZIJ
ŽIGA ROJEC, Iztok Fajfar
Doktorska disertacija
Oznake: avtomatska sinteza;analogna vezja;računalniško podprto načrtovanje;evolucijski algoritmi;veckriterijska optimizacija;hibridna optimizacija;
Načrtovanje analognih vezij je dolgotrajen proces, ki zahteva vso pozornost izkušenega razvijalca. Že desetletja velja, da načrtovalcu vezja v izdatni meri pomagajo namenske računalniške metode. Delo načrtovalca je tako rekoč revolucionaliziral simulator SPICE, ki uporabniku omogoča, da mu ob vsa ...

Evolutionary synthesis of failure-resilient analog circuits
Žiga Rojec, Iztok Fajfar, Arpad Bürmen
Izvirni znanstveni članek
Oznake: evolucijski algoritmi;načrtovanje analognih vezij;vezja odporna na okvare;algoritem NSGA-II;evolutionary algorithms;analog circuit synthesis;failure-resilient circuits;NSGA-II algorithm;
Analog circuit design requires large amounts of human knowledge. A special case of circuit design is the synthesis of robust and failure-resilient electronics. Evolutionary algorithms can aid designers in exploring topologies with new properties. Here, we show how to encode a circuit topology with a ...

Development and analysis of a modular LED array light source
Stefan Mitterhofer, Žiga Korošak, Žiga Rojec, Marko Jankovec, Marko Topič
Izvirni znanstveni članek
Oznake: LED;svetlobni viri;light sources;
Light emitting diodes (LEDs) have experienced rapid technological development in the past decade, making them a winning alternative to conventional light sources in many applications. LED arrays allow precise control of the desired irradiance profile in a target area by adjusting the position and ou ...

Meta-optimization of dimension adaptive parameter schema for Nelder–Mead algorithm in high-dimensional problems
Žiga Rojec, Tadej Tuma, Jernej Olenšek, Arpad Bürmen, Janez Puhan
Izvirni znanstveni članek
Oznake: meta optimizacija;algoritem Nelder-Mead;adaptivni parametri;visoko dimenzionalni optimizacijski problemi;meta-optimization;Nelder-Mead algorithm;adaptive parameter schema;high-dimensional optimization problems;
Although proposed more than half a century ago, the Nelder–Mead simplex search algorithm is still widely used. Four numeric constants define the operations and behavior of the algorithm. The algorithm with the original constant values performs fine on most low-dimensional, but poorly on high-dimensi ...

Synthesizing electrically equivalent circuits for use in electrochemical impedance spectroscopy through grammatical evolution
Matevž Kunaver, Mark Žic, Iztok Fajfar, Tadej Tuma, Arpad Bürmen, Vanja Subotić, Žiga Rojec
Izvirni znanstveni članek
Oznake: elektrokemična impedančna spektroskopija;gorivne celice;optimizacija;evolucijsko računanje;electrochemical impedance spectroscopy;fuel cells;optimization;evolutionary computation;
Electrochemical impedance spectroscopy (EIS) is an important electrochemical technique that is used to detect changes and ongoing processes in a given material. The main challenge of EIS is interpreting the collected measurements, which can be performed in several ways. This article focuses on the e ...

Imperative genetic programming
Iztok Fajfar, Žiga Rojec, Arpad Bürmen, Matevž Kunaver, Tadej Tuma, Sašo Tomažič, Janez Puhan
Izvirni znanstveni članek
Oznake: evolucijski algoritmi;drevesno genetsko programiranje;linearno genetsko programiranje;imperativno programiranje;evolutionary agorithms;tree genetic programming;linear genetic programming;imperative programming;
Genetic programming (GP) has a long-standing tradition in the evolution of computer programs, predominantly utilizing tree and linear paradigms, each with distinct advantages and limitations. Despite the rapid growth of the GP field, there have been disproportionately few attempts to evolve ’real’ T ...
