Perhaps you should try some spelling variations:
"using computational _ precoder program" » "and computational _ precoder program" (Expand search), "using computational _ proder program" (Expand search), "using computational _ recovery program" (Expand search), "using computational _ precoce programa" (Expand search)
"using lambda python python programming" » "using lambda pythons python programming" (Expand search), "using lambda piton python programming" (Expand search), "using lambda pitons python programming" (Expand search), "using lamb python python programming" (Expand search), "single lambda python python programming" (Expand search), "using lambert 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: (("using computational _ precoder program") OR ("using lambda python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational _ precoder program\") OR (\"using lambda python python programming\"))*".
• Removing quotes may allow a broader search: (( using computational _ precoder program ) OR ( using lambda python python programming ))*.
