Abstract.
We present two recent generalizations of Euclidean Distance optimization on algebraic varieties, exploring complementary directions.
The first, developed in Conditional Euclidean Distance Optimization via Relative Tangency (Di Rocco–Gustafsson–Sodomaco, 2023), introduces conditional tangency and the conditional ED-degree relative to a constraint variety.
The second, in Osculating Geometry and Higher-Order Distance Loci (Di Rocco–Rose–Sodomaco, 2025), replaces first-order normal spaces by higher-order osculating spaces, leading to the higher-order ED-degree.
Together, they outline a broader framework for metric algebraic geometry where tangency and contact govern optimization phenomena.
