Perhaps you should try some spelling variations:
"advanced implementation of loading problem" » "advancing implementation of loading problem" (Expand search), "and implementation of loading problem" (Expand search), "based implementation of loading problem" (Expand search), "advanced implementation of routing problem" (Expand search), "advanced implementation of planning problem" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python python python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced implementation of loading problem\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( advanced implementation of loading problem ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced implementation of loading problem") OR ("using python python python programming"))*.
