This paper presents an approach to synthesize the spatio-temporal dynamics of groups in standing conversation: four simple spatial rules form the building-blocks and a framework to automatically evolve rule and the parameter space by bootstrapping a-priori human judgment on the aesthetic quality of the simulations is introduced. The framework consists of a Genetic Algorithm and a scorer (fitness function) developed based on a machine learning system trained using human evaluations. The results of the study suggest that the framework is capable of deriving optimal rule and parameter combinations utilizing only a relatively small set of human scored training data. Further, the relationship between rule-complexity and visual fidelity is explored.</p></div><div class="article-ftr" style="padding-top: 4px; color: rgb(51, 51, 51); font-family: Arial, sans-serif; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 24.012800216674805px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;">&nbsp;</div>
