The Sample Average Approximation Method for Stochastic Discrete Optimization [PDF]

open access: yesSIAM Journal on Optimization, 2002
The authors study a Monte Carlo simulation-based approach to stochastic discrete optimization problems of the form \(\min_{x\in S}\{g(x):= E_PG(x, W)\}\), where \(W\) is a random vector having probability distribution \(P\), \(S\) is a finite set, \(G(x,w)\) is a real-valued function of two (vector) variables \(x\) and \(w\), and \(E_PG(x, W)= \int G(x,

Optimal Budget Allocation for Sample Average Approximation

open access: yesOperations Research, 2013
The sample average approximation approach to solving stochastic programs induces a sampling error, caused by replacing an expectation by a sample average, as well as an optimization error due to approximating the solution of the resulting sample average problem.

A hybrid genetic algorithm for scheduling jobs sharing multiple resources under uncertainty

open access: yesEURO Journal on Computational Optimization, 2022
This study addresses the scheduling problem where every job requires several types of resources. At every point in time, the capacity of resources is limited. When necessary, the capacity can be increased at a cost.

A Deficiency of the Weighted Sample Average Approximation (wSAA) Framework: Unveiling the Gap between Data-Driven Policies and Oracles

open access: yesApplied Sciences, 2023
This paper critically examines the weighted sample average approximation (wSAA) framework, a widely used approach in prescriptive analytics for managing uncertain optimization problems featuring non-linear objectives.

On Feasibility of Sample Average Approximation Solutions [PDF]

open access: yesSIAM Journal on Optimization, 2020
When there are infinitely many scenarios, the current studies of two-stage stochastic programming problems rely on the relatively complete recourse assumption. However, such assumption can be unrealistic for many real-world problems. This motivates us to study general stochastic programming problems where the sample average approximation (SAA ...

A Sample Average Approximation Approach for Event-Driven Probabilistic Constraint Programming [PDF]

open access: yes, 2005
We calculate the density profiles and density correlation functions of the one-dimensional Bose gas in a harmonic trap, using the exact finite-temperature solutions for the uniform case, and applying a local density approximation.
