Tuukka Korhonen

I am a computer science MSc student in University of Helsinki. I am currently working in the Constraint Reasoning and Optimization group. Recently, my research has focused on practical algorithms for exact solving of problems related to tree decompositions. Before that I worked on MaxSAT solving.






  • SMS - Exact algorithm for computing treedepth.
  • Triangulator - Implementation of the Bouchitté-Todinca algorithm for finding optimal triangulations.
  • MaxPre - MaxSAT preprocessor.


  • IPEC 2020 Best Paper Award and Best Student Paper Award
