My online article Funcoids and Reloids as well as my list of open problems are updated.
Added two open problems:
1. $latex (\mathsf{RLD})_{\mathrm{in}}$ is not a lower adjoint (in general)?
2. $latex (\mathsf{RLD})_{\mathrm{out}}$ is neither a lower adjoint nor an upper adjoint (in general)?
Also added an example proving that “$latex (\mathsf{FCD})$ does not preserve finite meets” and its consequence “$latex (\mathsf{FCD})$ is not an upper adjoint (in general)”.
There are other minor changes.
