The option markets offer a very interesting example of the adaptation of a population (the traders) to a complex environment, through trial and errors and natural selection (unefficent traders disappear quickly). The problem is the following: an ‘option’ is an insurance contract protecting its owner against the rise (or fall) of financial assets, such as stocks, currencies, etc. The problem of ...

Geometry with its formal, logical and spatial properties is well suited to be taught in an environment that includes dynamic geometry software (DGSs), automatic theorem provers (ATPs) and repositories of geometric problems (RGP). With the integration of those tools in a given learning management system (LMS), we can build an environment where the student is able to explore the built-in knowledg...

This paper describes a unified framework for the static and dynamic saliency detection by whitening both the chromatic characteristics and the spatio-temporal frequencies. This approach is grounded in the statistical adaptation to the input data, resembling the human visual system’s early codification. Our approach, AWS-D, outperforms state-ofthe-art models in the ability to predict human eye f...
