WebApr 28, 2024 · The optimality gap is the difference between the upper bound (found by a heuristic) and the lower bound (found by a partial exact method). ... Optimality clue matches with the standard definition of optimality in a large number of instances for DIMACS and RBCII benchmarks where the optimality is known. WebThe optimality conditions are derived by assuming that we are at an optimum point, and then studying the behavior of the functions and their derivatives at that point. The conditions that must be satisfied at the optimum point are called necessary. Stated differently, if a point does not satisfy the necessary conditions, it cannot be optimum.

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 … WebIn optimization problems in applied mathematics, the duality gap is the difference between the primal and dual solutions.
