Abstract: Abstract In the context of optimization under uncertainty, we consider various combinations of distribution estimation and resampling (bootstrap and bagging) for obtaining samples used to estimate a confidence interval for an optimality gap. This paper makes three experimental contributions to on-going research in data driven stochastic programming: (a) most of the combinations of distribution estimation and resampling result in algorithms that have not been published before, (b) within the algorithms, we describe innovations that improve performance, and (c) we provide open-source software implementations of the algorithms. Among others, three important conclusions can be drawn: using a smoothed point estimate for the optimality gap for the center of the confidence interval is preferable to a purely empirical estimate, bagging often performs better than bootstrap, and smoothed bagging sometimes performs better than bagging based directly on the data.
