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