Perhaps you should try some spelling variations:
"based computational coder allocation problem" » "and computational coder allocation problem" (Expand search), "by computational coder allocation problem" (Expand search), "based computational code allocation problem" (Expand search), "based computational codes allocation problem" (Expand search), "based computational model allocation problem" (Expand search), "based computational coder location problem" (Expand search), "based computational power allocation problem" (Expand search), "based computational order allocation problem" (Expand search), "based computational over allocation problem" (Expand search)
"using using python python programming" » "using using pythons python programming" (Expand search), "using using piton python programming" (Expand search), "using using pitons python programming" (Expand search), "using usando python python programming" (Expand search), "using in python python programming" (Expand search), "using fusing python python programming" (Expand search), "housing using python python programming" (Expand search), "nursing using 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 computational coder allocation problem\") OR (\"using using python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational coder allocation problem ) OR ( using using python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational coder allocation problem") OR ("using using python python programming"))*.
