Abstract: In this article2 I want to focus on the Ph.D. students who inspired Eric Postma and myself to pay attention to the topic of computers and intuition. During our time at Maastricht University five Ph.D. students (Rens Kortman, Michel van Dartel, Joyca Lacroix, Niek Bergboer, and Fred Hamburg) paved the way to formulate a basis for fertile ideas on intuition in relation to programs. In the period from January 1, 2008 to January 1, 2016 four Ph.D. students (Guido de Croon, Laurens van der Maaten, Igor Bereznoy, and Ruud Mattheij) positioned us by their research results on the right …track. The conclusion is provisional, but undeniable in my opinion: mental intuition is programmable. Show more

Abstract: In this study, we used fMRI technology, cognitive self-reporting, and gaze measurements to examine the changes in cognitive processing while people develop proficiency at the game Minishogi. We analyzed subjects’ performance by placing them in either a high-scoring group that performed relatively well in the final tournament and in answering intuitive problems or a low-scoring group that showed poorer performance. Our results show that the caudate nucleus was activated when subjects proficient at Minishogi answered intuitive problems. In addition, people with large caudate nuclei were better at answering intuitive problems in the early stages of learning; however, the caudate nucleus …size did not influence improvements in learning performance. As learning proceeded, the group with better results exhibited less gaze movement and required less time to recognize possible moves and decide on a move. Overall, the results suggested that people with good progress in learning Minishogi tend to require less time to recognize possible moves, show less gaze movement, anticipate more potential moves, and anticipate these moves more accurately.

Abstract: The article analyzes liberty races (semeai) in the game of Go. A rigorous treatment of positions with approach moves, but no ko revealed a class of positions not described in the literature before. The complete presented classification is simpler and more compact than the one used so far. This was achieved through a classification by the types of liberties and the order they are to be filled instead of a classification by group status. A principal difference to semeai without approach moves is that in the presence of approach moves and shared liberties and in the absence of …eyes, two different strategies are possible because the un-orthodox filling of shared liberties instead of outer liberties may be a better strategy.

Abstract: Many different mind sports programs participated in the 18th Computer Olympiad, held in Leiden, with programmers from all over the world. An extended blog2 gives details about the Draughts Championship that, with 12 participating programs, was the largest tournament of the Computer Olympiad. It gives the names of the programs and the programmers / operators, the gamescores, as well as the final results. The Blog is about the games with a selection made in such a way that all participating programs are involved. The idea is to illustrate to what extent the programs differ in playing strength, from …rather low to world championship level. In Table 1 we give the final standings. Show more
