Optimization-based convex relaxations for nonconvex parametric systems of ordinary differential equations

Y Song, KA Khan - Mathematical Programming, 2022 - Springer
Novel convex and concave relaxations are proposed for the solutions of parametric ordinary
differential equations (ODEs), to aid in furnishing bounding information for deterministic …
