  1. Fuzzy ReasoninginComputer Go Opening Stage Strategy P.Lekhavat and C.J.Hinde

  2. Game Objective • Surrounding most area on the board

  3. Game Stages • Opening game • Middle game • End game

  4. Opening game stage • Establish groups • Extend from own group • Prevent extension from opponent group • Reinforce weak group • Threaten invasion to opponent group

  5. Human reasoning • Territory • Potential • Urgent Move • Large Move • Framework

  6. Drawing Border

  7. Territory and Potential

  8. Stones potential

  9. Fuzzy Influence Conventional method Fuzzy Influence

  10. Using Fuzzy reasoning in Positional judgement Group A status - slightly weak, thin, pretty light Strategy for white - create base, enlarge eye space Strategy for black - threaten, neutralise group influence

  11. Hybrid SystemFuture development Fuzzy reasoning Pattern recognition Neural network Search tree Genetic algorithm

  12. Conclusion • Fuzzy reasoning was intended to be used to reduce search space by narrowing local objective • It need to be combined with other techniques to explore the best move • Also need automatic learning system improve it efficiency

  13. ?

  14. Middle game stage • Invade opponent territory • Defence their own territory

  15. End game stage • Close the gap between each groups
