I should have been more clear.  The tree structure is like this:
    
      /problem-dbase/problemXYZ/problem.tex

The latex source of the problem is in problem.tex and contains the line \graphicspath{{../problem-dbase/problemXYZ/}}. The enclosing folder is problemXYZ. All problems in the database are named problem.tex and are identified by the name of the enclosing folder. The root file resides in a folder at the same level as problem-dbase and calls this problem with the command

      \input{../problem-dbase/problemXYZ/problem.tex}

All of this miraculously works, but what I would like to do now is access from inside problem.tex the name of its enclosing folder and then pass it to \graphicspath, so that instead of hard-coding the name "problemXYZ" in the \graphicspath this would be set automatically in each latex run. I am probably asking for too much of a miracle...
