Evolution of Corewar Warriors2004algorithms, Computation genetic Evolutionary programming, Games and This paper analyzes corewar, a peculiar computer game where different programs fight in the memory of a virtual computer. An evolutionary assembly-program generator, is used to evolve efficient programs, and the game is exploited to evaluate new evolutionary techniques. The paper introduces a new migration model that exploits the polarization effect and a new hierarchical coarse-grained approach applicable whenever the final goal can be seen as a combination of semi-independent sub goals. Additionally, two general enhancements are proposed. Analyzed techniques are orthogonal and broadly applicable to different real-life contexts. Experimental results show that all these techniques are able to outperform a previous approach.http://www.bibsonomy.org/bibtex/299a78a6941ee5e32580169eed315bf01/brazovayeyebrazovayeye2008-06-19T17:35:00+02:00algorithms, genetic programming, games <span style="color:#555555;">Ilja <a href="http://www.bibsonomy.org/author/Bedner">Bedner</a> </span><em>Genetic Algorithms and Genetic Programming at Stanford 1997, </em><em>Stanford Bookstore, </em><em>Stanford, California, 94305-3079 USA, </em><em>17 March1997. </em>Thu Jun 19 17:35:00 CEST 2008Stanford, California, 94305-3079 USAGenetic Algorithms and Genetic Programming at Stanford 199717 MarchEvolving Light Cycle Algorithms1997algorithms, genetic programming, games Evolution of autonomous agents that must compete for survival in the light-cycle game as seen in the movie tronhttp://www.bibsonomy.org/bibtex/2b8939a7d8d2dc657d4f5fce0e1d22fe9/brazovayeyebrazovayeye2008-06-19T17:35:00+02:00genetic programming, agents, intelligent algorithms, Computation Evolutionary Games and <span style="color:#555555;">Andrei <a href="http://www.bibsonomy.org/author/Bajurnow">Bajurnow</a> and Vic <a href="http://www.bibsonomy.org/author/Ciesielski">Ciesielski</a> </span><em>Proceedings of the 2004 IEEE Congress on Evolutionary Computation, </em><em>page1828--1835. </em><em>Portland, Oregon, </em><em>IEEE Press, </em><em>20-23 June2004. </em>Thu Jun 19 17:35:00 CEST 2008Portland, OregonProceedings of the 2004 IEEE Congress on Evolutionary Computation20-23 June1828--1835Layered Learning for Evolving Goal Scoring Behavior in Soccer Players2004genetic programming, agents, intelligent algorithms, Computation Evolutionary Games and Layered learning allows decomposition of the stages of learning in a problem domain. We apply this technique to the evolution of goal scoring behavior in soccer players and show that layered learning is able to find solutions comparable to standard genetic programs more reliably. The solutions evolved with layers have a higher accuracy but do not make as many goal attempts. We compared three variations of layered learning and find that maintaining the population between layers as the encapsulated learnt layer is introduced to be the most computationally efficient. The quality of solutions found by layered learning did not exceed those of standard genetic programming in terms of goal scoring ability.http://www.bibsonomy.org/bibtex/2ac5f7552c7d03c7811c9ca8d2daac021/yishyish2008-06-05T13:40:11+02:00PatternLanguages IDR my OER planetpublications design CaseStudies educational jime08 patternlanguagenetwork language mythesis mathgamespatterns education casestudies opencontent patterns open Learning learning opensource wleformativeeassessment participatory Games Mathematics openeducationalresources JIME designpatterns workshops methodology <span style="color:#555555;">Yishay <a href="http://www.bibsonomy.org/author/Mor">Mor</a> and Niall <a href="http://www.bibsonomy.org/author/Winters">Winters</a> </span><em>Journal of Interactive Media</em>(<em>2008</em>)Thu Jun 05 13:40:11 CEST 2008Journal of Interactive MediaParticipatory design in open education: a workshop model for developing a pattern language2008PatternLanguages IDR my OER planetpublications design CaseStudies educational jime08 patternlanguagenetwork language mythesis mathgamespatterns education casestudies opencontent patterns open Learning learning opensource wleformativeeassessment participatory Games Mathematics openeducationalresources JIME designpatterns workshops methodology Technologically enhanced learning environments raise complex challenges for their designers, developers and users. Design patterns and pattern languages have recently emerged as a potential framework for addressing some of these challenges. However, the uptake of design patterns has been slow outside of the computer science community. We argue that this is largely a consequence of a weak positioning of pattern languages, as a form of delivering expert knowledge to layperson, and suggest an alternative view: the development of a pattern language as a community endeavour. In terms of open education, the workshop model can be viewed as an open production process for developing educational resources, in our case design patterns. We propose a model of pattern elicitation workshops, in which collaborative development of a pattern language provides a framework for sharing design knowledge within interdisciplinary communities. This model was iteratively developed at five international conferences. It was then postulated as a design pattern itself, encompassing a series of practices and a set of supporting tools. We believe this model could be applied in a broad range of communities concerned with the development of open digital educational resources.http://www.bibsonomy.org/bibtex/2e7b0fb6fe5b0554235f776706367786b/yishyish2008-05-30T04:12:20+02:00CSCL mythesis games design collaborative activity collaboration theory learning <span style="color:#555555;">Victor <a href="http://www.bibsonomy.org/author/Kaptelinin">Kaptelinin</a> and Michael <a href="http://www.bibsonomy.org/author/Cole">Cole</a> </span><em>CSCL 2: Carrying Forward the Conversation, </em><em>Lawrence Erlbaum Associates, </em><em>Mahwah, NJ, </em>(<em>2002</em>)Fri May 30 04:12:20 CEST 2008Mahwah, NJCSCL 2: Carrying Forward the Conversation297-310Individual and Collective Activities in Educational Computer Game Playing in Proceedings of Computer Game Playing2002CSCL mythesis games design collaborative activity collaboration theory learning http://www.bibsonomy.org/bibtex/29bff42e09feb136e3215eeaed7579be6/yishyish2008-05-30T04:11:24+02:00learning CnE07 games PlanetMakingStuffTogether computers mythesis design constructionism mathematics gmx game mathgamespatterns <span style="color:#555555;">Yasmin B. <a href="http://www.bibsonomy.org/author/Kafai">Kafai</a> </span><em>Lawrence Erlbaum Associates, </em><em>Mahwah, NJ, </em>(<em>1995</em>)Fri May 30 04:11:24 CEST 2008Mahwah, NJHardcoverMinds in Play: Computer Game Design As a Context for Children's Learning1995learning CnE07 games PlanetMakingStuffTogether computers mythesis design constructionism mathematics gmx game mathgamespatterns Video games more than any other media have become an essential part of contemporary children's culture. Whereas most research efforts have concentrated on discussing the effects of game playing, Minds in Play takes a close look at games as a context for learning by placing children in the roles of producers rather than consumers of games. Kafai follows a class of sixteen fourth-grade students from an inner-city public elementary school as they were programming games in Logo to teach fractions to third graders. In this context, programming became a medium for children's personal and creative expression: in the design of their games children engaged their fantasies and built relationships with other pockets of reality that went beyond traditional school approaches.http://www.bibsonomy.org/bibtex/2ce3f76908515a0a87a9a442741734246/yishyish2008-05-30T02:30:04+02:00educationalprogramming 3D mythesis gamesresearch games children programming gamestudies Alice <span style="color:#555555;">Stephen <a href="http://www.bibsonomy.org/author/Cooper">Cooper</a> and Wanda <a href="http://www.bibsonomy.org/author/Dann">Dann</a> and Randy <a href="http://www.bibsonomy.org/author/Pausch">Pausch</a> </span><em>Journal of Computing Sciences in Colleges</em><em>15(5):107-116</em>(<em>2000</em>)Fri May 30 02:30:04 CEST 2008Journal of Computing Sciences in Colleges5107-116Alice: a 3-D tool for introductory programming concepts152000educationalprogramming 3D mythesis gamesresearch games children programming gamestudies Alice http://www.bibsonomy.org/bibtex/223a821c366b42e64816d5fa6744e922f/yishyish2008-05-30T02:25:09+02:00gmr mathgamespatterns learning games mythesis mathematics gmx <span style="color:#555555;">David W. <a href="http://www.bibsonomy.org/author/Carraher">Carraher</a> and Darrell <a href="http://www.bibsonomy.org/author/Earnest">Earnest</a> </span><em>Proceedings of the 27th International Conference for the Psychology of Mathematics Education, </em><em>Honolulu, HI, </em>(<em>2003</em>)Fri May 30 02:25:09 CEST 2008Honolulu, HIProceedings of the 27th International Conference for the Psychology of Mathematics EducationGuess My Rule Revisited2003gmr mathgamespatterns learning games mythesis mathematics gmx We present classroom research on a variant of the guess-my-rule game, in which nine-yearl-old students make up linear functions and challenge classmates to determine their secret rule.

Despite significant advancement in ontology learning and human language technology, building ontologies, annotating data, and establishing alignments between multiple ontologies remain tasks that highly depend on human intelligence, both as a source of domain expertise and for specifying the results. This means that individuals need to contribute time, and sometimes other resources. Now, we can observe a sharp contrast in user interest in two branches of Web activity: While the “Web 2.0” movement lives from an unprecedented amount of contributions from Web users, we witness a substantial lack of user involvement in the aforementioned tasks . We assume that one cause of the latter is a lack of proper incentive structures, i.e., settings in which the perceived benefits outweigh the efforts for people to contribute. As a novel solution, we (1) propose to masquerade the core tasks of weaving the Semantic Web behind on-line, multi-player game scenarios, in order to create proper incentives for humans to get involved. Doing so, we adopt the findings from the already famous “games with a purpose” by von Ahn, who has shown that presenting a useful task, which requires human intelligence, in the form of an on-line game can motivate a large amount of people to work heavily on this task, and this for free. Then, we (2) describe our OntoGame prototypes, (3) provide preliminary evidence that users are willing to invest a lot of time into those games, (4) show that the users’ input creates reliable results, and (5) discuss how, by doing so, they unknowingly weave the Semantic Web.http://www.bibsonomy.org/bibtex/2b6ff642b6c1662b24c21130668eba5ef/yishyish2008-05-12T16:52:53+02:00games final report designpatterns design patterns kaleidoscope jime08 mathematical learning my mathgamespatterns <span style="color:#555555;">Dave <a href="http://www.bibsonomy.org/author/Pratt">Pratt</a> and Niall <a href="http://www.bibsonomy.org/author/Winters">Winters</a> and Efi <a href="http://www.bibsonomy.org/author/Alexopoulou">Alexopoulou</a> and James <a href="http://www.bibsonomy.org/author/Bligh">Bligh</a> and Staffan <a href="http://www.bibsonomy.org/author/Björk">Bj&#246;rk</a> and Michele <a href="http://www.bibsonomy.org/author/Cerulli">Cerulli</a> and Mark <a href="http://www.bibsonomy.org/author/Childs">Childs</a> and Augusto <a href="http://www.bibsonomy.org/author/Chioccariello">Chioccariello</a> and Vincent <a href="http://www.bibsonomy.org/author/Jonker">Jonker</a> and Chronis <a href="http://www.bibsonomy.org/author/Kynigos">Kynigos</a> and Berner <a href="http://www.bibsonomy.org/author/Lindström">Lindstr&#246;m</a> and Yishay <a href="http://www.bibsonomy.org/author/Mor">Mor</a> and Fionnuala <a href="http://www.bibsonomy.org/author/O&#039;Donnell">O'Donnell</a> and Brendan <a href="http://www.bibsonomy.org/author/Tangney">Tangney</a> and Monica <a href="http://www.bibsonomy.org/author/Wijers">Wijers</a> </span>(<em>2007</em>)Mon May 12 16:52:53 CEST 2008Kaleidoscope JEIRP on Learning Patterns for the Design and Deployment of Mathematical Games: Final Report2007games final report designpatterns design patterns kaleidoscope jime08 mathematical learning my mathgamespatterns Over the last few years have witnessed a growing recognition of the educational potential of computer games. However, it is generally agreed that the process of designing and deploying TEL resources generally and games for mathematical learning specifically is a difficult task. The Kaleidoscope project, "Learning patterns for the design and deployment of mathematical games", aims to investigate this problem. We work from the premise that designing and deploying games for mathematical learning requires the assimilation and integration of deep knowledge from diverse domains of expertise including mathematics, games development, software engineering, learning and teaching. We promote the use of a design patterns approach to address this problem. This deliverable reports on the project by presenting both a connected account of the prior deliverables and also a detailed description of the methodology involved in producing those deliverables. In terms of conducting the future work which this report envisages, the setting out of our methodology is seen by us as very significant. The central deliverable includes reference to a large set of learning patterns for use by educators, researchers, practitioners, designers and software developers when designing and deploying TEL-based mathematical games. Our pattern language is suggested as an enabling tool for good practice, by facilitating pattern-specific communication and knowledge sharing between participants. We provide a set of trails as a "way-in" to using the learning pattern language. We report in this methodology how the project has enabled the synergistic collaboration of what started out as two distinct strands: design and deployment, even to the extent that it is now difficult to identify those strands within the processes and deliverables of the project.
