Perhaps you should try some spelling variations:
"based computational on loading problem" » "and computational on loading problem" (Expand search), "by computational on loading problem" (Expand search), "based computational one loading problem" (Expand search), "based computacional on loading problem" (Expand search), "based computational and loading problem" (Expand search), "based computational on routing problem" (Expand search), "based computational on planning problem" (Expand search), "based computational in loading problem" (Expand search), "based computational on leading 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("based computational on loading problem") OR ("using python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational on loading problem\") OR (\"using python python python programming\"))".
• Removing quotes may allow a broader search: (( based computational on loading problem ) OR ( using python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computational on loading problem") OR ("using python python python programming"))*.
