We request that publications derived from the use of the MATPOWER Interior Point Solver (MIPS) explicitly acknowledge that fact by citing the following 2007 paper. H. Wang, C. E. Murillo-Sánchez, R. D. Zimmerman, R. J. Thomas, "On Computational Issues of Market-Based Optimal Power Flow," Power Systems, IEEE Transactions on, vol. 22, no. 3, pp. 1185-1193, Aug. 2007. doi: 10.1109/TPWRS.2007.901301. The MATPOWER Interior Point Solver (MIPS) User's Manual should also be cited explicitly in work that refers to or is derived from its content. The citation and DOI can be version-specific or general, as appropriate. For version 1.4, use: R. D. Zimmerman, H. Wang. MATPOWER Interior Point Solver (MIPS) User's Manual, Version 1.4. 2020. [Online]. Available: https://matpower.org/docs/MIPS-manual-1.4.pdf doi: 10.5281/zenodo.4073324 For a version non-specific citation, use the following citation and DOI, with replaced by the year of the most recent release: R. D. Zimmerman, H. Wang. MATPOWER Interior Point Solver (MIPS) User's Manual. . [Online]. Available: https://matpower.org/docs/MIPS-manual.pdf doi: 10.5281/zenodo.3236506 A list of versions of the User's Manual with release dates and version-specific DOI's can be found via the general DOI at https://doi.org/10.5281/zenodo.3236506.
