The 5Th Belgrade Chess Problems Festival Report by Milan Velimirović the Fifth Successive Festival Took Place from 2Nd to 4Th of May 2008
Mat Plus Review Summer 2008 The 5th Belgrade Chess Problems Festival Report by Milan Velimirović The fifth successive Festival took place from 2nd to 4th of May 2008. As usual a good number of guests from abroad were welcomed: Dinu-Ioan Nicula (ROM), Aleksander Leontyev (RUS), Andrey Selivanov (RUS), Eric Huber (ROM), Fadil Abdurahmanović (BIH), Iļja Ketris (LAT), Ivan Denkovski (MAK), Kostas Prentos (GRE), Michal Dragoun (CZE), Piotr Murdzia (POL), Valery Kopyl with his lovely daughter Valeria (UKR) and Živko Janevski (MAK). You may have noticed the exception from the alphabetical order of that list, but there is a good reason for it: Dinu-Ioan Nicula is the only foreign composer who has attended all five Festivals, and if he comes again next year the organizers could consider the idea of promoting him into an honorary participant. Anyway, all guests have been treated by the home team in a traditionally warm and friendly way. For the record, the participants from Serbia were: Bogoljub Trifunović, Borislav Gađanski, Borislav Ilinčić, Božidar Brujić, Božidar Šoškić, Branislav Đurašević, Darko Šaljić, Dragoljub Đokić, Goran Janković, Goran M. Todorović, Goran Škare, Igor Spirić, Joza Tucakov, Marjan Kovačević, Mihajlo Milanović, Milan Velimirović, Miodrag Radomirović, Mirko Miljanić, Nikola Miljaković, Nikola Petković, Petar Opening speech: Milan Milićević, president Šoškić, Radomir Mićunović, Slobodan of Chess club “Beograd Beopublikum”, Šaletić, Stevan B. Bokan, Tomislav Petrović, accompanied by Marjan Kovačević Vladimir Podinić and Zoran Sibinović. The programme was very busy and here is a brief report of all the events. Friday, May 2nd, 16:00. All participants were allowed to take part in a Machine Gun Solving event. -

Chess Problem Composing Steps
Appendix A Chess Problem Composing Steps Chess problems for this research were composed automatically using CHESTHETICA (see Fig. A.1) following the essential steps below. It is a modi- fication of the approach used in (Iqbal 2011). The problems composed are limited to orthodox mate-in-3 problems in standard international chess. 1. Obtain the two new DSNS strings produced from the DSNS process (see Sect. 3.1). 2. Set the total number of white pieces and black pieces that can be used in the composition. There are two attribute values pertaining to these features in each DSNS string. (a) For example, if in string 1 the white piece count is 5 and in string 2 the white piece count is 10, the range possible for this computer composition is between 5 and 10. The same for the black pieces. 3. Calculate the total Shannon value of the white pieces and then the black pieces in both strings and get the average of each. Use these average values to determine the number of piece permutations (i.e. combinations of different pieces) that satisfy them. (a) For example, an average value of 10 for white could mean having a bishop, two knights and a pawn whereas an average value of 9 for black could mean having just a queen. The total number of piece permutations possible for both the white and black pieces here is totaled. (b) This total will equal the number of times the same pair of DSNS strings is used in attempting to generate a composition. So, in principle, every legal piece combination can be tested. -

The Digital Synaptic Neural Substrate: A New Approach to Computational Creativity Azlan Iqbal1, Matej Guid2, Simon Colton3, Jana Krivec4, Shazril Azman 5 and Boshra Haghighi6 ABSTRACT We introduce a new artificial intelligence (AI) approach or technique termed, the ‘Digital Synaptic Neural Substrate’ (DSNS). This technique uses selected attributes from objects in various domains (e.g. chess problems, classical music, renowned artworks) and recombines them in such a way as to generate new attributes that can then, in principle, be used to create novel objects of creative value to humans relating to any one of the source domains. This allows some of the burden of creative content generation to be passed from humans to machines. The approach was tested primarily in the domain of chess problem composition. We used the DSNS technique to automatically compose numerous sets of chess problems based on attributes extracted and recombined from chess problems and tournament games by humans, renowned paintings, computer-evolved abstract art, photographs of people, and classical music tracks. The quality of these generated chess problems was then assessed automatically using an existing and experimentally-validated computational chess aesthetics model. They were also assessed by human experts in the domain. The results suggest that attributes collected and recombined from chess and other domains using the DSNS approach can indeed be used to automatically generate chess problems of reasonably high aesthetic quality. In particular, a low quality chess source (i.e. tournament game sequences between weak players) used in combination with actual photographs of people was able to produce three-move chess problems of comparable quality or better to those generated using a high quality chess source (i.e. -
