ITC2007 solver description: a hybrid approach

  • Tomáš MüllerEmail author


This paper provides a brief description of a constraint-based solver that was successfully applied by the author to the problem instances in all three tracks of the International Timetabling Competition 2007 (For more details see the official competition website at The solver presented in this paper was among the finalists in all three tracks and the winner of two.
