Plantinga-Vegter algorithm is a commonly used subdivision based method for meshing curves and surfaces. First rigorous complexity analysis of the method was provided by Burr, Gao, and Tsigaridas ( using the worst-case bit size complexity model. I'd like present beyond-worst-case analysis point of view on the complexity of Plantinga-Vegter algorithm using techniques from complexity theory of numerical algorithms and high dimensional probability. The ideas and techniques introduced in the talk are somewhat general and could be applied to a more broad family of symbolic-numeric algorithms.

Joint work with Felipe Cucker ( City University of Hong Kong) and Josue Tonelli-Cueto (Inria Paris & IMJ-PRG).
