Algorithmic geometry is a field of research at the intersection of mathematics and computer science, with strong links to geometry and topology, statistics, combinatorics, algorithmics, graph theory and optimal transport, among others. The aim of the Journées de Géométrie Algorithmique (JGA) is to bring together the French community of researchers in algorithmic geometry. One of the main objectives is to create a collaborative working environment for young students and researchers, enabling them to present their results and interact easily with other members of the community.
