Rahman Tektas

MSc Computer Science student at Université libre de Bruxelles (ULB), specializing in Artificial Intelligence & Data Science.

I am mainly interested in database systems, data-intensive software, algorithms and optimization, and applied machine learning.

Selected projects

Native PostgreSQL extension written in C for genomic sequence data.

  • custom dna, kmer, and qkmer types
  • PostgreSQL operators and functions
  • hash, B-tree, and SP-GiST index support
  • SQL tests and Docker-based development workflow

C · PostgreSQL · SQL · Docker · Linux

Implementation and experimental comparison of local-search methods for the Linear Ordering Problem.

  • transpose, exchange, and insert neighborhoods
  • first- and best-improvement search
  • Variable Neighborhood Descent
  • benchmark automation and statistical analysis

C · R · Combinatorial Optimization · Benchmarking

Experimental Python implementation of a cooperative-agent model for repeated bimatrix games.

  • particle-based opponent modelling
  • Nash-equilibrium computation with Lemke–Howson
  • repeated-game simulation and evaluation
  • reproducible tests and experiment scripts

Python · Game Theory · Nash Equilibria · Simulation

Collaborative Python chess application supporting human play, Minimax-based opponents, and a neural-network mode. My contributions are preserved in the repository history.
