We develop some algorithms to determine viability kernels in large dimensions. Various strategies have been used, based on SVM (support vector machines, Deffuant et al. 2007), kd-Trees (Alvarez et al. 2013) or recursive simplex stars (Deffuant 2017). Our work consists in designing these algorithms, determining mathematically their convergence properties, and developing computer software that implement these algorithms. Approximated viability kernels can then be compared and manipulated with our ViNO platform.
