In this contribution, we aim to understand some of the factors contributing to the hardness of a problem instance, and to use machine … Nettet30. sep. 2016 · Lemma (Instance-dependent lower bound): Let ν = (Pi)i, ν ′ = (P ′ i) be K -action stochastic bandit environments that differ only the distribution of the rewards for action i ∈ [K]. Further, assume that i is suboptimal in ν and is optimal in ν ′, and in particular i is the unique optimal action in ν ′.

Nettetthen ℓp minimisation is “instance optimal of order m with constant C for the ℓq (quasi)norm” for the matrix Φ [5]. It has been shown that instance optimality is related to a robust null space property (e.g. [3, 5]). The matrix Φ satisﬁes the robust NSP of order m with constant ρ < 1 for the ℓp norm, or concisely Φ ∈ RobustNSP ... NettetAlthough we do not know the optimal solution for the generated large instances, obviously we can certify the optimality of the heuristic solution in case a solution with an objective function value equal to zero is identified. We can see that, as the size of the instance increases, the number of zero-solutions improves.
