I am a Professor in the Computer Systems Department at Technical University of Sofia, Bulgaria
I lecture at the Department of Computer Systems, Technical University-Sofia for undergraduate, graduate students, and MSc degree students. I also lectured in University of Food Technologies, Plovdiv, Bulgaria and University of Vaxjo, Sweden. Lectured in a seminar in MICHIGAN TECHNOLOGICAL UNIVERSITY, USA. I have developed algorithms and software, named VSEP, for graph automorphism group and graph isomorphism. They are opened source, located in section My Programs.
My current research interests include mainly graph algorithms (isomorphism, graph automorphism group (generators, orbits and order of graph automorphism group ), subgraph problem, maximum common subgraph problem, determining unital designs and maximal arcs in projective planes, determining hamiltonian paths and circuits)
· Algorithms and software for automatic generation of algorithms for problems in some fields of mathematics and computer science (Artificial Intelligence);
· Algorithms and software for syntactic analysis of sentences in Bulgarian language (Artificial Intelligence);
· Algorithms and software for modeling and analysis of electrical and electronic circuits;
· Algorithms and software for Determining Protein Structure Similarity:
· Algorithms and software for finding Unital Designs, Maximal Arcs and Disjoint Maximal Arcs in Projective Planes
