Perhaps you should try some spelling variations:
"using computational coder allocation problem" » "and computational coder allocation problem" (Expand search), "using computational code allocation problem" (Expand search), "using computational codes allocation problem" (Expand search), "using computational model allocation problem" (Expand search), "using computational coder location problem" (Expand search), "using computational power allocation problem" (Expand search), "using computational order allocation problem" (Expand search), "using computational over allocation problem" (Expand search)
"using visual python python programming" » "using via python python programming" (Expand search), "using visual path python programming" (Expand search), "using visual pythons python programming" (Expand search), "using visual piton python programming" (Expand search), "using visual pitons python programming" (Expand search), "using virtual 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: (("using computational coder allocation problem") OR ("using visual python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational coder allocation problem\") OR (\"using visual python python programming\"))*".
• Removing quotes may allow a broader search: (( using computational coder allocation problem ) OR ( using visual python python programming ))*.
