We start with a classical theme that was featured in the January 2020 issue of the Notices of the A merican Mathematical Society\, namely the 3264 conics that are tangent to five given conics in the plane. We discuss the computation of these conics \, by solving a system of polynomial equations with numerical methods that are fast and reliable. In our discussion we will focus on the role of app lied algebraic geometry in statistics and optimization\, starting from the role of linear spaces of symmetric matrices (LSSM) for Gaussian models an d semidefinite programming.\n LOCATION:https://researchseminars.org/talk/tmc-dls/3/ END:VEVENT END:VCALENDAR
