Here, one of the most famous GGP frameworks, The General Video Game AI Competition (GVGAI) Framework, is used in order to design controllers for Atari 2600 inspired games. Recent advancements in the literature of GVGAI showed that the Rolling Horizon Evolution Algorithm (RHEA) is competitive when compared to other methods, encouraging the use and the research by improvements for this method. The use of a 1-Step-Look-ahead approach and a Redundant Action Avoidance policy during the creation of new individuals are proposed in this paper. The 1-step-look-ahead technique improves the action selection after the shift of the individual in RHEA with the shift buffer enhancement (RHEA-SB), and the redundant action avoidance policy decreases the chance of spatial redundant actions within the individual. Also, a parameter analysis of RHEA-SB is performed here, where different values of population size, depth of simulations, and number of individuals that remains in the population are evaluated. Results show that using 1-Step-Look-ahead and a redundant action avoidance policy improves the quality of the solutions found when compared to the original algorithm.","PeriodicalId":170922,"journal":{"name":"2018 17th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130829391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A number of predictive techniques were developed to deliver the best experience for the players. With the growing numbers of players and the complexity of the worlds, the limitations of such techniques, like network delay, consistency, responsivity and bandwidth cost, become evident. The main technique used nowadays is called Dead Reckoning (DR) and was firstly presented decades ago. Based on it a variety of authors proposed improvements to the prediction method, culminating on Kharitonov’s proposal of the Motion-Aware Adaptive Dead Reckoning (MAADR) technique. The author’s evaluation did not consider latency, an important factor that affects the consistency (i.e. veracity) of the information and the Quality of Experience for the players. The proposal of this paper is to evaluate both the MAADR and DR prediction techniques in 4 situations ranging from simple to complex movement patterns, with 0 to 300ms of network delay. The results show that the MAADR performance is superior when compared to the classic algorithm for each situation and each different latency evaluated. It shows that the classic DR presents a large decay in precision within medium and high latencies and it is not ideal in situations with great intolerances to network delay. Because of the obtained results, it is recommended the usage of the MAADR technique when medium and high latencies are expected or when there is an intolerance for the loss of the Quality of Experience.","PeriodicalId":170922,"journal":{"name":"2018 17th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128710747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is the need for a deeper understanding that these characteristics alone do not provide. Another problem is the use of predefined profiles that might be oversimplified or too embracing. This paper investigates players profiles based on their gameplay data, besides demographics, using an educational math game as a testbed. Thus, problems such as noise, mixed data types and high dimensionality must be tackled. To this end, we investigated two feature extraction methods to mitigate these difficulties, Principal Component Analysis (PCA) and Features Agglomeration (FA). Then, two unsupervised learning algorithms were used to find the profiles in our experiments, showing that both PCA and FA improved clustering performance, wherein the best results indicated four profiles: advanced, skilled, beginners and intermediated. Our findings provide game designers with insights about playing styles, can be used to adapt the game in real-time and to assess how distinct players profiles perform in the educational subject, as well as their playing performance.","PeriodicalId":170922,"journal":{"name":"2018 17th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122678515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In interactive storytelling, the player is presented with a set of options to help direct the narrative, and the Drama Manager (DM) is responsible for controlling the narrative trajectories the user will experience. This work proposes a DM based on a genetic algorithm, which will be able to present non-deterministic plot lines to the player, increasing replayability. The proposed DM will follow the Anthropological Structures of the Imaginary proposed by Durand to guide the narrative, which will be the basis for a player model. Experiments were performed both with synthetic datasets as well as eleven players. The results show the GA finds subsets of plot lines that are not far from the optimum while increasing replayability. Qualitative analyses of the players preference considering the three regiments that defined Durand’s theory show it is appropriate to model the players preferences in interactive storytelling.","PeriodicalId":170922,"journal":{"name":"2018 17th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121371782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
