Perhaps you should try some spelling variations:
"using computation in coverage problems" » "using computational in coverage problems" (Expand search), "using imputation in coverage problems" (Expand search), "using compilation in coverage problems" (Expand search), "using computation in coverage problem" (Expand search), "using computation in covering problems" (Expand search), "using computation in covering problem" (Expand search), "using computation and coverage problems" (Expand search), "using computation of coverage problems" (Expand search)
"using codigo python python programming" » "using codigo pythons python programming" (Expand search), "using codigo piton python programming" (Expand search), "using codigo pitons python programming" (Expand search), "using indigo python python programming" (Expand search), "using coding python python programming" (Expand search), "using codium 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: "((\"using computation in coverage problems\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( using computation in coverage problems ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation in coverage problems") OR ("using codigo python python programming"))*.
