Re-examining of Moffitt's theory of delinquency through agent based modeling

JN Leaw, RP Ang, VS Huan, WT Chan, SA Cheong - PLoS one, 2015 - journals.plos.org
Moffitt’s theory of delinquency suggests that at-risk youths can be divided into two groups, the
adolescence- limited group and the life-course-persistent group, predetermined at a young …

Strategic insights from playing quantum tic-tac-toe

JN Leaw, SA Cheong - Journal of Physics A: Mathematical and …, 2010 - iopscience.iop.org
In this paper, we perform a minimalistic quantization of the classical game of tic-tac-toe, by
allowing superpositions of classical moves. In order for the quantum game to reduce properly …
