Perhaps you should try some spelling variations:
"based computation _ precoder program" » "based computational _ precoder program" (Expand search), "based competition _ precoder program" (Expand search), "based compilation _ precoder program" (Expand search), "based computation _ proder program" (Expand search), "based computation _ recovery program" (Expand search), "based computation _ precoce programa" (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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("based computation _ precoder program") OR ("using in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computation _ precoder program\") OR (\"using in python python programming\"))*".
• Removing quotes may allow a broader search: (( based computation _ precoder program ) OR ( using in python python programming ))*.
