Perhaps you should try some spelling variations:
"based implementation and routing programming" » "and implementation and routing programming" (Expand search), "based implementation and routine programming" (Expand search), "based implementation and routines programming" (Expand search), "based implementation and computing programming" (Expand search), "based implementation of routing programming" (Expand search), "based implementation arc routing programming" (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: "((\"based implementation and routing programming\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( based implementation and routing programming ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based implementation and routing programming") OR ("using coding python python programming"))*.
