Perhaps you should try some spelling variations:
"_ computational in precoder program" » "_ computational and precoder program" (Expand search), "_ computational _ precoder program" (Expand search), "_ computational 3d precoder program" (Expand search), "_ computational in proder program" (Expand search), "_ computational in recovery program" (Expand search), "_ computational in precoce programa" (Expand search), "_ computational in premodern program" (Expand search), "_ computational to precoder program" (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: (("_ computational in precoder program") OR ("using in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ computational in precoder program\") OR (\"using in python python programming\"))*".
• Removing quotes may allow a broader search: (( _ computational in precoder program ) OR ( using in python python programming ))*.
