Competitively chasing convex bodies
WebAbstract. Let be a family of sets in some metric space. In the -chasing problem, an online algorithm observes a request sequence of sets in and responds (online) by giving a sequence of points in these sets. The movement cost is the distance between consecutive such points. The competitive ratio is the worst case ratio (over request sequences) … WebNov 2, 2024 · In convex body chasing, for each timestep t∈ N, a convex body K_t⊆ R^d is given as a request, and the player picks a point x_t∈ K_t. The player aims to ensure that the total distance ∑_t=0^T-1 x_t-x_t+1 is within a bounded ratio of the smallest possible offline solution. ...

The player aims to maintain a constant competitive ratio against the minimum cost possible in hindsight, i.e. knowing all requests in advance. The existence of a finite competitive ratio for convex body chasing was first conjectured in 1991 by Friedman and Linial.
