Gabriel Istrate

My CV.

I have recently published papers at conferences such as AAMAS (2019,2020,2021), ICALP, ESA, SAT, IPEC, CPM.
I have recently been a P.C. member (or organizer) of events such as AAMAS 2021, AAAI 2021, SOFSEM 2019, MCU 2018, FOIKS 2018, ALGOCLOUD 2017, Diaspora Științifică 2016, MCU 2015 and, of course, many editions of SYNASC and MATCOS.

I was funded by research projects such as:

  • ATCO “Advanced Techniques in Combinatorial Optimization and Computational Complexity”. 2017-2019.
  • STRUCTCOMB,  “Structure and computational difficulty in combinatorial optimization: an interdisciplinary approach”. 2012-2016.
  •  PHASETRANS, “Phase transitions in computational complexity and formal verification: towards generic and realistic approaches”.  Marie Curie IRG project. 2007-2009.

Recent research interests (and some recent papers)

I see myself as a generalist,with a long and eclectic list of interests. I have published papers in physics journals, in computer networking and artificial intelligence conferences, I have worked on proof complexity, analysis of real functions, hope to publish some day  in journals in economics (mainly game theory) and analytic philosophy.

Still, a significant fraction of my interests lies in Theoretical Computer Science, mainly in algorithms and computational complexity. On the other hand, many of the models and problems I cared about have an interdisciplinary nature, relating  to the Physics of Complex Systems or to Social Dynamics (or both 😀). Through my recent work on Game Theory I  also became interested in Artificial Intelligence (particularly from a symbolic perspective).

Here a list of all my research papers , and another one of papers grouped by research topic.
