  skos:definition """En géométrie affine, une combinaison convexe de certains points est un barycentre de ces points avec des coefficients tous positifs. L'ensemble des combinaisons convexes de ces points est donc leur enveloppe convexe. 
<br/>(Wikipedia, L'Encylopédie Libre, <a href="https://fr.wikipedia.org/wiki/Combinaison_convexe">https://fr.wikipedia.org/wiki/Combinaison_convexe</a>)"""@fr, """In convex geometry and vector algebra, a convex combination is a linear combination of points (which can be vectors, scalars, or more generally points in an affine space) where all coefficients are non-negative and sum to 1. In other words, the operation is equivalent to a standard weighted average, but whose weights are expressed as a percent of the total weight, instead of as a fraction of the count of the weights as in a standard weighted average.
