Perhaps you should try some spelling variations:
"based computation in compression problem" » "based computation in comprehnsion problem" (Expand search), "based computation in comprehension problem" (Expand search), "based computation in completion problem" (Expand search), "based computational in compression problem" (Expand search), "based competition in compression problem" (Expand search), "based compilation in compression problem" (Expand search), "based computation and compression problem" (Expand search), "based computation of compression problem" (Expand search), "based imputation in compression problem" (Expand search), "based computation image compression problem" (Expand search), "based computation axial compression 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 compression problem\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation in compression problem ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation in compression problem") OR ("using python python python programming"))*.
