This paper proposes a new algorithm to compute the resilience of a social system or an ecosystem when it is defined in the framework of the mathematical viability theory. It is applied to the problem of language coexistence: Although bilingual societies do exist, many languages have disappeared and some seem endangered presently. Mathematical models of(More)
Abduction is a backward chaining inference, finding the best explanations of an observation with regard to a knowledge base in a two-steps process: i) hypotheses generation, and ii) explanations selection according to a minimality criterion. A propositional abduction problem P is a tuple 〈V,O, T 〉 [3], where V is a set of variables, T denotes the background(More)
Models of social systems generally contain free parameters that cannot be evaluated directly from data. A calibration phase is therefore necessary to assess the capacity of the model to produce the expected dynamics. However, despite the high computational cost of this calibration it doesn't produce a global picture of the relationship between the parameter(More)
