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 coupled python python programming" » "using coupled method python programming" (Expand search), "using coupled position python programming" (Expand search), "in coupled python python programming" (Expand search), "using coupled pythons python programming" (Expand search), "using coupled piton python programming" (Expand search), "using coupled pitons 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 coupled python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational coder allocation problem\") OR (\"using coupled python python programming\"))".
• Removing quotes may allow a broader search: (( using computational coder allocation problem ) OR ( using coupled python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("using computational coder allocation problem") OR ("using coupled python python programming"))*.
