Center node: "experiments with synchronizing automata"
  Abstract: We have improved an algorithm generating synchronizing automata with a large length of the shortest reset words. This has been done by refining some known results concerning bounds on the reset length. Our improvements make possible to consider a number of conjectures and open questions concerning synchronizing automata, checking them for automata with a small number of states and discussing the results. In particular, we have verified the Cerný conjecture for all binary automata with at most 12 states, and all ternary automata with at most 8 states.
