Asynchronous Lagragian Scenario Decompostion: SMIP Instances

This repository contains stochastic mixed-integer programming (SMIP) instances for developing/testing/benchmarking solution algorithms. The SMIP instances are in SMPS format with fixed column width and 'EXPLICIT' period declaration. Instances are organized in 4 tar files: 'DCAP.tar': 12 two-stage stochastic integer programs arising in dynamic capacity acquisition and allocation applications, part of SIPLIB, but re-formatted in this work. 'SSLP.tar': 7 two-stage stochastic mixed-integer programs arising in stochastic server location problems, part of SIPLIB, but re-formatted in this work. 'WECC.tar': 24 stochastic unit commitment instances of the Western Electricity Coordinating Council (WECC) system. 'CWE.tar': 24 stochastic unit commitment instances for the Central Western European (CWE) system.
