Perhaps you should try some spelling variations:
"developing computation in coverage problem" » "developing computational in coverage problem" (Expand search), "developing population in coverage problem" (Expand search), "developing communication in coverage problem" (Expand search), "developing computation in covering problem" (Expand search), "developing computation in covering problems" (Expand search), "developing computation in coverage from" (Expand search), "developing computation and coverage problem" (Expand search), "developing computation of coverage problem" (Expand search), "developing imputation in coverage 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: "((\"developing computation in coverage problem\") OR (\"using using python python programming\"))~".
• Removing quotes may allow a broader search: (( developing computation in coverage problem ) OR ( using using python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("developing computation in coverage problem") OR ("using using python python programming"))*.
