# 2018-12-12 **Portfolio Optimization - Use Case**
Thank you to [Laura Vana](https://bach.wu.ac.at/d/research/ma/10862/#publications.) for contributing a use case about portfolio optimization!

# 2018-06-19 **ROI.plugin.neos**
**ROI.plugin.neos** was releasd on CRAN. More information about
**ROI.plugin.neos** can be found in the 
[manual](https://CRAN.R-project.org/package=ROI.plugin.neos/ROI.plugin.neos.pdf)
and the 
[vignette](https://CRAN.R-project.org/package=ROI.plugin.neos/vignettes/ROI.plugin.neos_Introduction.pdf).


# 2018-04-23 **ROI.plugin.qpoases**
**ROI.plugin.qpoases** was releasd on CRAN. It provides a **`C++`** interface 
to [qpOASES](https://projects.coin-or.org/qpOASES/) which is 
part of the Computational Infrastructure for Operations Research (COIN-OR) project.
**ROI.plugin.qpoases** can be used to solve quadratic problems and due to the 
flipping bounds strategy, **ROI.plugin.qpoases** can also be used to find 
critical points of non-convex QP problems. For more information for 
**`qpOASES`** we refer to the [**qpOASES**-Manual](https://www.coin-or.org/qpOASES/doc/3.2/manual.pdf),
more information about
**ROI.plugin.qpoases** can be found in the 
[**ROI.plugin.qpoases**-Manual](https://CRAN.R-project.org/package=ROI.plugin.qpoases/ROI.plugin.qpoases.pdf).
