Investigating evolutionary checkers by incorporating individual and social learning, N-tuple systems and a round robin tournament

In recent years, much research attention has been paid to evolving self-learning game players. Fogel's Blondie24 is just one demonstration of a real success in this field and it has inspired many other scientists. In this thesis, artificial neural networks are employed to evolve game playing strategies for the game of checkers by introducing a league structure into the learning phase of a system based on Blondie24. We believe that this helps eliminate some of the randomness in the evolution. The best player obtained is tested against an evolutionary checkers program based on Blondie24. The results obtained are promising. In addition, we introduce an individual and social learning mechanism into the learning phase of the evolutionary checkers system. The best player obtained is tested against an implementation of an evolutionary checkers program, and also against a player, which utilises a round robin tournament. The results are promising. N-tuple systems are also investigated and are used as position value functions for the game of checkers. The architecture of the n-tuple is utilises temporal difference learning. The best player obtained is compared with an implementation of evolutionary checkers program based on Blondie24, and also against a Blondie24 inspired player, which utilises a round robin tournament. The results are promising. We also address the question of whether piece difference and the look-ahead depth are important factors in the Blondie24 architecture. Our experiments show that piece difference and the look-ahead depth have a significant effect on learning abilities

On Wargaming

Wargames are as old as civilization—and perhaps older. In his informative and entertaining Public Broadcasting series Connections, James Burke argued that the first invention, the one that enabled all later inventions, was the plow. It allowed agriculture, and as agriculture permitted denser populations, the frequency of inventions increased, due either to “connecting” with new applications or combining with other inventions to create one that was greater than the sum of its parts.https://digital-commons.usnwc.edu/usnwc-newport-papers/1043/thumbnail.jp

Changing Our Tune: A Music-Based Approach to Teaching, Learning, and Resolving Conflict

The need for change within the legal profession and legal education is critical. To remain relevant and responsive to twenty-first century challenges and complexities the next generation of professionals must be creative, imaginative, and innovative thinkers. Emotional and social intelligence, the ability to collaboratively problem-solve, negotiate, and mediate complex conflict are essential skills needed for success particularly in increasingly settlement-oriented environments. Studies and reports have noted, however, that practitioners are lacking these key skills. How can these new perspectives and essential skills be taught and developed? This mixed methods research study involved five professional musicians and thirty-eight first year law school students. Data from musicians regarding effective collaborative music-making and most valued capacities for achieving optimal outcomes informed the design of a comparative teaching study that explored the effects of introducing a music-based metaphor and pedagogical approach to teaching, learning, and resolving conflict. The study provided insights into whether and how the musical ensemble metaphor might assist in shifting adversarial combative and competitive frames toward more collaborative, settlement-oriented mindsets and whether and how music-infused pedagogy might assist in developing enhanced skills and practice behaviours that lead to more desirable outcomes. Results from this initial study suggest that non-musicians in non-musical environments are able to learn from musical metaphors and concepts related to ensemble music-making and that such learning – cognitive, affective, and behavioural – translates into changed and more effective behaviour in practice. In simulated scenarios students exposed to the musical metaphor and other music-based learning appeared to outperform their colleagues not exposed to similar music-based learning. Engagement with music appears to reconnect people to their creative potential and lead them to see the efficacy of employing creative thinking in professional environments where analytical and critical thinking have generally been over-emphasized. There are indications that experiences with collaborative approaches to conflict have the potential to shift traditional norms and behaviours. This study and its results are of interest to those in the field of law, conflict resolution, those exploring arts-based teaching and learning in other professions, such as leadership and organizational behaviour, to music educators, and educators at all levels generally

Eye quietness and quiet eye in expert and novice golf performance: an electrooculographic analysis

Quiet eye (QE) is the final ocular fixation on the target of an action (e.g., the ball in golf putting). Camerabased eye-tracking studies have consistently found longer QE durations in experts than novices; however, mechanisms underlying QE are not known. To offer a new perspective we examined the feasibility of measuring the QE using electrooculography (EOG) and developed an index to assess ocular activity across time: eye quietness (EQ). Ten expert and ten novice golfers putted 60 balls to a 2.4 m distant hole. Horizontal EOG (2ms resolution) was recorded from two electrodes placed on the outer sides of the eyes. QE duration was measured using a EOG voltage threshold and comprised the sum of the pre-movement and post-movement initiation components. EQ was computed as the standard deviation of the EOG in 0.5 s bins from –4 to +2 s, relative to backswing initiation: lower values indicate less movement of the eyes, hence greater quietness. Finally, we measured club-ball address and swing durations. T-tests showed that total QE did not differ between groups (p = .31); however, experts had marginally shorter pre-movement QE (p = .08) and longer post-movement QE (p < .001) than novices. A group × time ANOVA revealed that experts had less EQ before backswing initiation and greater EQ after backswing initiation (p = .002). QE durations were inversely correlated with EQ from –1.5 to 1 s (rs = –.48 - –.90, ps = .03 - .001). Experts had longer swing durations than novices (p = .01) and, importantly, swing durations correlated positively with post-movement QE (r = .52, p = .02) and negatively with EQ from 0.5 to 1s (r = –.63, p = .003). This study demonstrates the feasibility of measuring ocular activity using EOG and validates EQ as an index of ocular activity. Its findings challenge the dominant perspective on QE and provide new evidence that expert-novice differences in ocular activity may reflect differences in the kinematics of how experts and novices execute skills
