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