Perhaps you should try some spelling variations:
"based computation in allocation problem" » "based computation in location problem" (Expand search), "based computational in allocation problem" (Expand search), "based competition in allocation problem" (Expand search), "based compilation in allocation problem" (Expand search), "based computation and allocation problem" (Expand search), "based computation of allocation problem" (Expand search), "based imputation in allocation problem" (Expand search), "based computation _ 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 computation in allocation problem\") OR (\"using using python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation in allocation problem ) OR ( using using python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation in allocation problem") OR ("using using python python programming"))*.
