Reproducibility Variable Result LLM Response
Research Type Experimental We evaluate our results on synthetic experiments, where the feasible set is defined by knapsack and matching constraints. We compare the performance of our greedy heuristic for deterministic and stochastic delays of the same mean. In both experimental settings we used k = 50 arms, exact oracles for the underlying feasibility problem ( = β = 1) and averaged the results over 50 trials. The empirical ratio in both settings is computed against an LP relaxation (see appendix D for a detailed description of the experimental settings). In the case of stochastic delays, the empirical ratio is slightly worse but regret is smaller (Fig. 1).
