If there might be some ambiguity about which software package you require, please clarify by including a web page of a company that sells it or other identifying information. If you need a specific version or optional components of the software, mention those as well. If there is an alternate package that could be used for your work, mention that, with a ranking if possible (for example "MATLAB, Mathematica or Maple, with MATLAB preferred ). If you are not sure about what specific commerical software could be used state the requirements (non-linear optimization library callable from C++) and we can have a follow-up discussion after investigating the possibilities. If you know whether you will be using a serial, shared-memory parallel or distributed parallel version of the software, that is also useful information to include.
If you choose the "Other" option, please clarify the role of the software in your research project, using the space provided below. Also feel free to elaborate if you have chosen one of the other options.
