Perhaps you should try some spelling variations:
"modeling computational _ precoder program" » "modelo computacional _ precoder program" (Expand search), "modelado computacional _ precoder program" (Expand search), "modelacion computacional _ precoder program" (Expand search), "modeling computational _ proder program" (Expand search), "modeling computational _ recovery program" (Expand search), "modeling computational _ 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: (("modeling computational _ precoder program") OR ("using in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modeling computational _ precoder program\") OR (\"using in python python programming\"))".
• Removing quotes may allow a broader search: (( modeling computational _ precoder program ) OR ( using in python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("modeling computational _ precoder program") OR ("using in python python programming"))*.
