Daniel Nov´ak,Ph.D. and to all participants that were involved in testing of my application for their precious time. I must express my profound gratitude to my loved ones for their support and continuous encouragement throughout my years of study. This accomplishment would not have been possible without them. Thank you. 5 Declaration I declare that I have developed this thesis on my own and that I have stated all the information sources in accordance with the methodological guideline of adhering to ethical principles during the preparation of university theses. In Prague 09.01.2017 Author 6 Abstract This bachelor thesis deals with analysis and implementation of mobile application that allows visually impaired people to play chess on their smart phones. The application con- trol is performed using special gestures and text{to{speech engine as a sound accompanier. For human against computer game mode I have used currently the best game engine called Stockfish. The application is developed under Android mobile platform.

Hans Olav Lahlums Generelle Forhndsomtale Av Eliteklassen 2005
Hans Olav Lahlums generelle forhåndsomtale av eliteklassen 2005 Eliteklassen 2005 tangerer fjorårets deltakerrekord på 22 spillere - og det avspeiler gledeligvis en åpenbar nivåhevning sammenlignet med situasjonen for få år tilbake. Ettersom regjerende mester GM Berge Østenstad grunnet forhåpentligvis forbigående motivasjon- og formabstinens står over årets NM, beholder eliteklassen fra Molde i 2004 statusen som historiens sterkeste. Men det er med knepen margin til årets utgave, som med seks GM-er og fem IM-er er klart sterkere enn alle utgaver fra før 2004 - og dertil historisk som den første med kvinnelig deltakelse! Hva angår kongepokalen er eksperttipsene sjeldent entydige før start i eliteklassen 2005: Kampen om førsteplassen vil ifølge de aller fleste deltakerne stå mellom den fortsatt toppratede sjakkongen GM Simen Agdestein, sjakkronprinsen GM Magnus Carlsen og vårens formmester GM Leif Erlend Johannessen. At årets Norgesmester finnes blant de tre synes overveiende sannsynlig, men at det blir akkurat de tre som står igjen på pallen til premieutdelingen er langt mindre åpenbart: Tross laber aktivitet er bunnsolide GM Einar Gausel en formidabel utfordrer i så måte, og den kronisk uberegnelige nye GM Kjetil A Lie så vel som den kronisk uberegnelige gamle GM Rune Djurhuus har også åpenbart potensiale for en medalje. I klassen for GM-nappkandidater er den formsterke IM-duoen Helge A Nordahl og Frode Elsness de mest spennende kandidatene å følge, men resultatene fra vinterens seriesjakk indikerer at eks-Norgesmester Roy Fyllingen også bør holdes under overvåkning. IM Bjarke Barth Sahl (tidligere Kristensen) har nok GM-napp, men mangler desto mer ELO på å bli GM, så feltets eldste spiller kan i år konsentrere seg om å spille for en premieplass. -

BULLETIN 8 Søndag 7
BULLETIN 8 Søndag 7. juli. Pris kr 20 Den beste vant Norgesmestertittelen og Kongepokalen gikk til stormester Jon Ludvig Hammer (23) som hadde god kontroll på partituviklingen i siste runde mot Rune Djurhuus og sikret seg seieren med en remis. Dermed kunne publikum glede seg over å få hylle en Norgesmester og ikke bare stikkampspillere som i utrolige åtte av de ni foregående årene. Årets nybakte norgesmester Jon Ludvig Hammer med kongepokal på toppen av pallen. De øvrige premierte elitespillerne er fra venstre Frode Elsness, Atle Grønn, Leif E. Johannessen, Rune Djurhuus, Berge Østenstad, Frode Urkedal og Aryan Tari. Det var heller ikke mye tvil om at Jon Ludvig var en fortjent og riktig mester av Lillehammer 2013. Han spilte nok jevnt best, ble den eneste ubeseirede spilleren i klassen og endte med ett helt poengs margin til Frode Elsness, som han i et svakt øyeblikk avga en kanskje noe unødvendig remis til. For norsk sjakks del var det også best at den yngste og mest seriøst satsende stormesteren vår ved siden av Magnus Carlsen lyktes med å legge feltet bak seg og bli norgesmester for første gang. Gledelig var det også at yngstemann, Aryan Tari, bekreftet den jevnt over sterke framgangen sin med en lovende IMtittel etter sitt tredje napp i tittelen på drøyt tre måneder. Siste og avgjørende remis Fartsfylt kafésjakk Hvit: Jon Ludvig Hammer, OSS Espen Thorstensen fra Kongsvinger revansjerte en bukk i 5. runde i klasse med en imponerende seier i Svart: Rune Djurhuus, Nordstrand kveldens Kafesjakkturnering.

Turkish Journal of Computer and Mathematics Education Vol.12 No.2 (2021), 2814-2819 Research Article Can Chess Ever Be Solved Naveen Kumar1, Bhayaa Sharma2 1,2Department of Mathematics, University Institute of Sciences, Chandigarh University, Gharuan, Mohali, Punjab-140413, India [email protected], [email protected] Article History: Received: 11 January 2021; Accepted: 27 February 2021; Published online: 5 April 2021 Abstract: Data Science and Artificial Intelligence have been all over the world lately,in almost every possible field be it finance,education,entertainment,healthcare,astronomy, astrology, and many more sports is no exception. With so much data, statistics, and analysis available in this particular field, when everything is being recorded it has become easier for team selectors, broadcasters, audience, sponsors, most importantly for players themselves to prepare against various opponents. Even the analysis has improved over the period of time with the evolvement of AI, not only analysis one can even predict the things with the insights available. This is not even restricted to this,nowadays players are trained in such a manner that they are capable of taking the most feasible and rational decisions in any given situation. Chess is one of those sports that depend on calculations, algorithms, analysis, decisions etc. Being said that whenever the analysis is involved, we have always improvised on the techniques. Algorithms are somethingwhich can be solved with the help of various software, does that imply that chess can be fully solved,in simple words does that mean that if both the players play the best moves respectively then the game must end in a draw or does that mean that white wins having the first move advantage. -

The 17Th Top Chess Engine Championship: TCEC17
The 17th Top Chess Engine Championship: TCEC17 Guy Haworth1 and Nelson Hernandez Reading, UK and Maryland, USA TCEC Season 17 started on January 1st, 2020 with a radically new structure: classic ‘CPU’ engines with ‘Shannon AB’ ancestry and ‘GPU, neural network’ engines had their separate parallel routes to an enlarged Premier Division and the Superfinal. Figs. 1 and 3 and Table 1 provide the logos and details on the field of 40 engines. L1 L2{ QL Fig. 1. The logos for the engines originally in the Qualification League and Leagues 1 and 2. Through the generous sponsorship of ‘noobpwnftw’, TCEC benefitted from a significant platform upgrade. On the CPU side, 4x Intel (2016) Xeon 4xE5-4669v4 processors enabled 176 threads rather than the previous 43 and the Syzygy ‘EGT’ endgame tables were promoted from SSD to 1TB RAM. The previous Windows Server 2012 R2 operating system was replaced by CentOS Linux release 7.7.1908 (Core) as the latter eased the administrators’ tasks and enabled more nodes/sec in the engine- searches. The move to Linux challenged a number of engine authors who we hope will be back in TCEC18. 1 Corresponding author: [email protected] Table 1. The TCEC17 engines (CPW, 2020).
