Sentient Sketchbook was introduced during the 2013 Conference on the Foundations of Digital Games [1]. The technology for generating suggestions has been presented in papers for the EvoStar [2] conference (2013) and the Genetic and Evolutionary Computation [3] Conference (2013), and in greater detail in the Evolutionary Computation Journal [4]. The role of suggestions as a prompt for mixed-initiative co-creativity was formalized in a paper for the 2014 Conference on the Foundations of Digital Games [5]. The best student paper of the 2013 conference on AI and Interactive Digital Entertainment elaborated on how the evaluations of Sentient Sketchbook can be generalized for other types of game levels such as dungeons or first-person shooter arenas [6]. Extensions of the current version of Sentient Sketchbook were presented in the 2014 conference on Computational Intelligence and Games: one paper [7] proposed additions which take the human designer's style, process and visual goals into account, and won the best paper award, while the other paper [8] proposed an algorithm which simultaneously targets strategic quality and visual diversity and was also nominated for best paper. Another extension of the map sketch concept was presented in [9], where level evolution was carried out in phases, with each phase refining map sketches evolved in the previous phase. The AI behind Sentient Sketchbook has also been modularized as a webservice, available here and documented in [10].
