An amazing article, via Nelson Minar -- careful examination of the evolution of chess programs over the past 8 years appears to show clear signs of code/algorithm copying and unauthorised reverse engineering -- by many of the developers. 'Dr Søren Riis of Queen Mary University in London shows how most programs (legally) profited from Fruit, and subsequently much more so from the (illegally) reverse engineered Rybka. Yet it is Vasik Rajlich who was investigated, found guilty of plagiarism, banned for life, stripped of his titles, and vilified in the international press – for a five-year-old alleged tournament rule violation. Ironic.'
