WebJul 14, 2024 · I am teaching myself branch and bound and keep coming across the term optimality gap. So I am looking at an example (shown in the image below) and would like to know if my analysis is correct. I think the arrows drawn in the example are misleading me but I have found a way for it to make sense to me and I would like to confirm that I am … WebDec 27, 2024 · In our analysis we consider a continuous optimality measure related to some optimization algorithm. One possible continuous optimality measure, associated with the generalized conditional gradient algorithm, is the surrogate optimality gap. Definition 1

This paper proposes auction-based mechanisms as decentralized resource allocation methods that significantly reduce the optimality gap of restoration plans devised by Judgment Call methods. In particular, we propose that, before devising plans, decision-makers participate in an auction by declaring …
WebMar 7, 2024 · In this paper, we study gap-dependent regret guarantees for risk-sensitive reinforcement learning based on the entropic risk measure. We propose a novel definition of sub-optimality gaps, which we call cascaded gaps, and we discuss their key components that adapt to the underlying structures of the problem. Based on the cascaded gaps, we …
