Perhaps you should try some spelling variations:
"advanced computation in routing problem" » "advanced computations in routing problem" (Expand search), "advanced computational in routing problem" (Expand search), "advance computational in routing problem" (Expand search), "advanced computation and routing problem" (Expand search), "advanced computation of routing problem" (Expand search), "advanced imputation in routing problem" (Expand search), "advanced computation in routine problem" (Expand search), "advanced computation in rooting problem" (Expand search), "advanced computation on routing problem" (Expand search)
"using modeling vpython python programming" » "using modeling method python programming" (Expand search), "using model vpython python programming" (Expand search), "using modern vpython python programming" (Expand search), "using models vpython python programming" (Expand search), "using modeling python python programming" (Expand search), "using modeling pythons python programming" (Expand search), "using modeling piton 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 computation in routing problem\") OR (\"using modeling vpython python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation in routing problem ) OR ( using modeling vpython python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation in routing problem") OR ("using modeling vpython python programming"))*.
