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