Perhaps you should try some spelling variations:
"computing implementation in routing problem" » "computational implementation in routing problem" (Expand search), "planning implementation in routing problem" (Expand search), "learning implementation in routing problem" (Expand search), "computing implementation and routing problem" (Expand search), "computing implementation of routing problem" (Expand search), "computing implementation in routine problem" (Expand search), "computing implementation in rooting problem" (Expand search), "computing implementation on routing problem" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking 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: "((\"computing implementation in routing problem\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( computing implementation in routing problem ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("computing implementation in routing problem") OR ("using coding python python programming"))*.
