Algebraic Curve Computation and Optimization

Algebraic Curve Computation and Optimization encompasses the study of polynomial equations in two variables and the development of efficient methods to analyse, represent and manipulate their solutions. Central tasks include determining parametrisations that express curves in rational or analytic form, computing asymptotic behaviour at infinity, and optimising the complexity and numerical stability of these processes. Advances in symbolic and numerical algorithms have enabled the computation of curve invariants such as genus and singularity structure, and the design of transformations that simplify geometric and topological analyses. Applications span computer‐aided geometric design, robotics path planning, image processing, and the solution of differential systems with algebraic constraints. By integrating techniques from algebraic geometry, computational algebra and optimisation theory, researchers strive to reduce computational cost, improve robustness against perturbations and extend methodologies to curves with transcendental or piecewise‐defined parametrisations. Recent work also explores the interaction between discrete parameter specialisations and the preservation of geometric invariants, enhancing the reliability of design and simulation frameworks in engineering and scientific computing.
