Perhaps you should try some spelling variations:
"_ computational coder allocation problem" » "_ computational code allocation problem" (Expand search), "_ computational codes allocation problem" (Expand search), "_ computational model allocation problem" (Expand search), "_ computational coder location problem" (Expand search), "_ computational power allocation problem" (Expand search), "_ computational order allocation problem" (Expand search), "_ computational over allocation problem" (Expand search)
"using visible python python programming" » "using available python python programming" (Expand search), "in visible python python programming" (Expand search), "using visual python python programming" (Expand search), "using visible pythons python programming" (Expand search), "using visible piton python programming" (Expand search), "using visible 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: (("_ computational coder allocation problem") OR ("using visible python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ computational coder allocation problem\") OR (\"using visible python python programming\"))".
• Removing quotes may allow a broader search: (( _ computational coder allocation problem ) OR ( using visible python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("_ computational coder allocation problem") OR ("using visible python python programming"))*.
